A college administrator wanted to make all freshmen live on campus, because he thought that this would lead to better study habits and better grades. He commissioned a study that found a P‑value less than 0.05 for the difference in GPAs between freshmen who lived on campus and freshmen who commuted. The average GPA for the random sample of freshmen who lived on campus was 2.53, and the average GPA for the random sample of freshmen who commuted was 2.51. When he presented his findings, his idea was rejected.
What reason was he most likely given for this rejection?
a. The calculations from the study were likely incorrect.
b. The difference was not practically significant.
c. The difference was not statistically significant.
Homework Answers
The most likely reason for this rejection was that the difference was not statistically significantly so option c.

A study is conducted to determine what percentage of students live on campus at a large university. In a random sample found of 50 male students, it was found that that 27 of them lived on campus. In a sample of 55 female students, it was found that 40 lived on campus. At the .05 level of significance, does this sample data provide sufficient evidence to conclude that a difference exists between the proportion of male students who live on...

ndependent random samples are taken at a university to compare the average GPA of seniors to the average GPA of sophomores. Given a 95% confidence interval for the difference between the true average GPAs (seniors - sophomores) of (0, 1.13), what can you conclude? Question 9 options: 1) We are 95% confident that the difference between the two sample GPAs falls within the interval. 2) We are 95% confident that the average GPA of seniors is greater than the average...

A researcher wanted to see if live reggae music improved students’ math test scores. He selected a sample of 61 students from his university and gave them a math test. The students then studied for two and a half hours while an acoustic reggae band played quietly. The students then took another math test of the same difficulty. The researcher’s variable was the change in test score for each student — a positive change meant the student did better, while...

Suppose administrators at a large school district decide to institute mandatory study halls at their middle schools in an effort to boost their students' academic performance. After one year, a guidance counselor decides to test whether students' grade point averages (GPAs) have improved compared to the previous school year. The counselor selects a random sample of 30 eighth-graders from throughout the district who were also enrolled in the district for seventh grade. He records their GPAs for grades seven and...

Context: You own three Chick-Fil-A franchises. In your sales district, you know that the average weekly sales are $542,000. One of your stores (Clarkesville store) brought in an average of $530,000 each week in the last year. Assume that you conducted the most appropriate test and found the following: Z = 3.32 Lower Critical Value = -2.00 Upper Critical Value = 2.00 P-value = 0.0015 Level of significance = 0.05 ----------------------------------------------------------- 1a) Based on this information, which of the following...

8. A random sample of 25 college males was obtained and each was
asked to report their actual height and what they wished as their
ideal height. A 95% confidence interval for μd= average difference
between their ideal and actual heights was 0.8" to 2.2". Based on
this interval, which one of the null hypotheses below (versus a
two-sided alternative)can be rejected?
A. H0: μd= 0.5
B. H0: μd= 1.0
C. H0: μd= 1.5

You are curious about the average number of yards Matthew Stafford throws for each game for the Detroit Lions. You randomly select 23 games and see that the average yards per game is 344.5 with a standard deviation of 27.8 yards. You want to create a 95% confidence interval for the true average number of yards per game he throws. What is the margin of error for this estimate? Question 1 options: 1) 1.5833 2) 5.7967 3) 12.0216 4) 9.9538...
