Using the phosphorus data from the table, calculate the percentage of each phosphorus source that enters the Mississippi from the city of St. Paul.
Answers
Answer/Explanation:
% of each Nitrogen source = amount of Nitrogen from each source/total amount if Nitrogen × 100
% of Nitrogen from atmospheric deposition:
\( \frac{1,300}{7,400}*100 = \frac{130,000}{7,400} = 17.57 \)
Approximately 18%
% of Nitrogen from household pet waste:
\( \frac{2,100}{7,400}*100 = \frac{210,000}{7,400} = 28.38 \)
Approximately 28%
% of Nitrogen from residential fertilizer:
\( \frac{3,800}{7,400}*100 = \frac{380,000}{7,400} = 51.35 \)
Approximately 51%
% of Nitrogen from weathering:
0%
% of Nitrogen from county compost:
\( \frac{200}{7,400}*100 = \frac{20,000}{7,400} = 2.70 \)

A psychological researcher designs a study to determine whether positive feedback affects student test performance. The researcher requires each student enrolled in AP Psychology to participate. Students are divided into 3 groups—positive feedback, negative feedback, and no feedback. After completing the Module 1 FRQ, students in Group 1 are provided with positive feedback about their work and encouraged to keep working hard. Students in Group 2 are given criticisms of their writing and encouraged to rethink taking the course. Students in Group 3 are only given a numeric score, no written feedback. After reading the feedback, participants complete a survey measuring self-esteem and take their Module 1 Exam. Test scores are compared for the three groups. Following the test, all participants are debriefed and the true nature of the research explained. Results of the study indicate that participants who received positive feedback on their FRQs scored on average of 8 points higher than students who received negative feedback or no feedback at all. Which of the following violations to ethical guidelines is committed in the study described?
A) Confidentiality
B) Exposure to harmful procedures
C) Failure to debrief
D) Inappropriate use of deception
E) Voluntary participation
Answers
Answer: Option D
Explanation:
The test groups were divided into three groups the positive, negative and no feedback groups. The positive groups got better scores than compared to the negative feedback group and no feedback group.
The ethical guidelines that is violated is the inappropriate use of deception. The group that got negative feedback. Intentionally their morale was downsided.
Deception is not ethical in case of psychological experiments however, in some cases it is allowed to keep the experiment unbiased.
Answer:
B) Exposure to harmful procedures
Explanation:
You are mentally hurting the children's self esteem, hence unethical. Not A or C or D because you gave them a proper debriefing and confidentiality is fine. Not E because not all AP Psych students were forced; rather, they were given the option to participate. B is correct.
Problem 1. 2, here's a table from the previous screen describe any patterns you notice on the table
Answers
Here is the table given in the previous screen. x y 1 4 2 7 3 10 4 13 5 16 6 19 7 22 8 25 9 28 10 31The data set in the table above is known as a linear function.
A linear function is one in which the data points lie on a straight line. If you examine the data set, you'll notice that the slope is equal to 3, which means that for every increase of 1 in the x value, the y value increases by 3. The graph of this equation would be a straight line that goes upward. As the value of x increases, the value of y increases as well, and the two variables are proportional.
The relationship between x and y is thus linear. Therefore, in the given table, we notice a pattern that shows how the value of y is related to the value of x. As x increases, y also increases in a linear fashion, and we can calculate y by using the equation y=3x +1.

The expected difference in GPA is 1.4, and the standard deviation of the differences is 0.41.
What would be the effect on the above parameters?Expected difference in GPA: 1.4Standard deviation of the differences: 0.5If the art department lowered its grades by 10% and the mathematics department increased its grades by 1 quality point each, the expected difference in GPA would decrease to 0.4 and the standard deviation of the differences would increase to 0.6.Expected Difference: 0.4Standard Deviation: 0.4By lowering the art department's grades by 10%, the expected difference in GPA between the art and mathematics classes will decrease by 0.1. The standard deviation of the differences between the two classes will also decrease by 0.1. This is because the art GPA has a lower average, so when the grades are lowered, the difference between the two classes is more likely to be lower than the previous value. On the other hand, increasing the mathematics department's grades by 1 quality point will increase the expected difference in GPA by 0.1 and the standard deviation of the differences between the two classes by 0.1. This is because the mathematics GPA has a higher average, so when the grades are increased, the difference between the two classes is more likely to be higher than the previous value. Overall, the change in grades will cause a slight decrease in the expected difference in GPA and a slight increase in the standard deviation of the differences between the two classes.To learn more about Simpson's paradox refer to:

Answers
Note that if depositors withdraw $4,000 from Otis Bank the initial change in M1 money supply would be $4000.
How is this so?When depositors remove funds from a bank, the quantity of money stored in M1, which comprises currency in circulation and demand deposits, decreases. Because the withdrawn amount is no longer accessible for immediate consumption, the M1 money supply falls.
The money supply refers to all the amount of all the currency and other liquid assets in a country's economy at the time the money supply is calculated.

The alternate method for constructing confidence intervals for small sample sizes involves adding four additional observations to the original sample, calculating a new sample proportion, and constructing a confidence interval using the new proportion and a modified formula.

Throughout the book and in these final chapters, Krakauer points out several instances where Chris McCandless was in the vicinity of where he was trying to go or was closer to help than he knew. Why might Krakauer dwell on tracing just how close Chris was to being saved or coming out alive?
Answers
Answer:
Krakauer is concluding, from what he knows of McCandless, that he is a sane individual, if not brilliant. However, Krakauer had an experience very similar and can relate to McCandless and his hunger for adventure. He does not think McCandless was batty but as an explorer The narrative works almost as a countdown, starting on July 8, 1992 with McCandless’s return to the bus after finding the Teklanika too flooded, pauses the narrative for a discussion of his physical decline, then enumerating each remaining day at a time. His quotations from McCandless’s diary adds to the poignancy and drama of these last days, as does the inclusion of the detail that McCandless wanted to leave the wild. His diary records that he is now trapped, despite his desire to return, lending the chapter a fatal tone at the same time that Krakauer builds narrative urgency.

The uninsured motorist fee
Options:

none of the above
Answers
The uninsured motorist fee does not provide you with insurance coverage in the event of a crash, allow you to drive an uninsured vehicle, or pay when you are the victim of a crash involving an uninsured vehicle. Therefore, the correct option is "none of the above."
The uninsured motorist fee is a specific fee that is required in some states for individuals who choose not to purchase auto insurance. Instead of buying insurance coverage, they pay this fee as an alternative. However, it is important to note that the fee itself does not provide any insurance benefits or coverage. It is simply a fee that exempts individuals from the legal requirement of having auto insurance in those particular states.
While the fee may allow you to legally drive an uninsured vehicle by fulfilling the state's requirements, it does not offer any financial protection or coverage in the event of a crash. If you are involved in an accident with an uninsured motorist, you would not have the benefit of insurance coverage from the fee. It is always advisable to have proper auto insurance to protect yourself financially in case of accidents.
