Problem 2-23

Suppose that the national average for the math portion of the College Board's SAT is 534. The College Board periodically rescales the test scores such that the standard deviation is approximately 50. Answer the following questions using a bell-shaped distribution and the empirical rule for the math test scores.

If required, round your answers to two decimal places.

In a effort to better predict the demand for courses offered by a certain MBA program, it was hypothesized that students' academic backgrounds affect their choice of MBA major, thus, their course selection. A random sample of last year's MBA students was selected. The results are shown below. (A) State the null hypothesis and alternative hypothesis. (B) USING EXCEL Can we infer that undergraduate degree affects MBA students' course preferences?

1. A psychologist has developed a personality test on which scores can range from 0 to 200. The mean score of well-adjusted people is 100. It is assumed that the less well-adjusted an individual is, the more the individual’s score will differ from the mean value. The Dean of Students at XYZ University is interested in discovering whether the students at XYZ are well-adjusted, on average. Fifteen students are randomly sampled. Their scores are: 80, 60, 120, 140, 200, 70, 30, 180, 70, 150, 20, 50, 170, 90, 130.
   1. Estimate the magnitude of the effect using Cohen’s d. What does your number mean?
   2. Construct the 95% confidence interval to estimate mean adjustment. State the outcome in English.
   3. In what way is the question tested in this problem not a sensible question?

Identify the most relevant source of bias in each situation. a. A survey asks the following: Should the death penalty be permitted if innocent people might die? b. A study seeks to investigate whether a new pain medication is safe to market to the public. They test by randomly selecting 300 people who identify as men from a set of volunteers. c. A survey asks how many sexual partners a person has had in the last year. d. A radio station asks listeners to phone in their response to a daily poll. e. A substitute teacher wants to know how students in the class did on their last test. The teacher asks the 10 students sitting in the front row to state their latest test score.
f. High school students are asked if they have consumed alcohol in the last two weeks.

A recent study of high school students shows the percentage of females and males who have at LEAST one notation in their school record for inappropriate behavior. A simple random sample of high school students was interviewed. The students were asked whether they had a notation for inappropriate behavior in their school record. Of the 100 females, 21 answered yes, as did 145 of the 400 males.

Part A: Construct and interpret a 99% confidence interval for the difference in population proportions of females and males who have at LEAST one notation for inappropriate behavior. Be sure to state the parameter, check conditions, perform calculations, and make conclusion(s). (8 points)

Part B: Does your interval from part A give convincing evidence of a difference between the population proportions? Explain. (2 points) (10 points)

Create a mini debate transcript for this two students:

Imagine this scenario: You are attending a local psychology conference and you find two graduate level psychology students entered in a hot debate, with a crowd of people around them. You are curious and come closer to see what everyone is interested in. You find that they are debating the work and personality of BF Skinner. One of the students, Rick Nilsen claims that Skinner was a cool headed scientist who based his opinions about the human being only on observable behavior. The other student, Blanca Alvarez, says that Skinner was not just as simple as he seemed. He believed in behaviorism, just like other people believed in Marxism or any other –ism. • What points would each one make?

TOPIC: Depression among students who arrived in some Australian University

Write a reflection on your personal response to the interview experience on depression among international students in University. For example you can reflect on your question delivery and engagement with the participants or your listening skills. What did you do well? What did you find easy? What can you improve on?

Note: We conduct Interview with 3 international students and some questions were, what do you know about depression? how often do you feel sad? what are the main reason having such issues? views regarding causes of depresion? have consult anyone regarding your problem?

INTERVIEW TECHNIQUE: FACE TO FACE

Suppose that the national average for the math portion of the College Board's SAT is 538. The College Board periodically rescales the test scores such that the standard deviation is approximately 100. Answer the following questions using a bell-shaped distribution and the empirical rule for the math test scores.

If required, round your answers to two decimal places.
