Part I: Sampling

Your college wants to gather student opinions about parking for students on campus. It is not practical to contact all the students. For this assignment, complete the following items:

Design a bad sample. In a short paragraph, design how you would create a sample of students to answer your survey on parking. This should be an example of a bad sample design.

Design a good sample. Do the same as above, but discuss a sample design that would be considered a good sample design. Discuss how the good sample design differs from the bad sample design.

Based on the limited amount of available student parking spaces on the GSU campus, students are being encouraged to ride their bikes (when appropriate). The administration conducted a survey to determine the proportion of students who ride a bike to campus. Of the 123 students surveyed 5 rides a bike to campus. Which of the following is a reason the administration should not calculate a confidence interval to estimate the proportion of all students who ride a bike to campus?...

Suppose a student carrying a flu virus returns to an isolated college campus of 1000 students.

Suppose a student carrying a flu virus returns to an isolated college campus of 1000 students. Determine a differential equation governing the number of students x(t) who have contracted the flu if the rate at which the disease spreads is proportional to the number of interactions between the number of students with the flu and the number of students who have not yet been exposed to it

The student academic group on a college campus claims that freshman students study at least 2.5 hours per day, on average. One Introduction to Statistics class was skeptical. The class took a random sample of 30 freshman students and found a mean study time of 137 minutes with a standard deviation of 45 minutes. At α = 0.01 level, is the student academic group’s claim correct? Calculate the p-value.

Sampling Distributions and the Central Limit Theorem: The National Survey of Student Engagement asks college students questions about the quality of their education. In 2018, NSSE reported the following result about college freshman: During the current school year, about how often have you used numerical information to examine a real-world problem or issue (unemployment, climate change, public health, etc.)? Mean: 2.29 SD: .92 These results were based on a survey of over 500,000 students from 725 institutions. Suppose we want...

A campus student club distributed material about membership to new students attending an orientation meeting. Of those receiving this material, 35% were men and 65% were women. Subsequently, it was found that 8% of the men and 11% of the women who received this material joined the club. Complete parts a and b below. a. Find the probability that a randomly chosen new student who receives the membership material will join the club. nothing (Round to four decimal places as...

Economics: Supply and Demand USF issues parking permits to allow students to park on campus. The price of the permit is set by college administrators at their discretion, they do not consider market conditions. At the current price, some students complain that there aren’t enough spaces for them to park. A) Describe this situation in economic terms and describe what this implies about the market equilibrium and the price of a parking permit. B) Should the price of a parking...

Many University campuses sell parking permits to their students allowing them to park on campus in designated areas. Although most students complain about the relatively high cost of these permits, what annoys many of these students even more is that after having paid for their permits, vacant parking spaces in the designated lots are very difficult to find during much of the day. Many end up having to park off campus anyway, where permits are not required. Assuming the University...

As part of a school project students will be randomly sampling from the students in the class. The assignment is to estimate the proportion of students who play on a sports team. Each student will randomly select 6 students. One student found out that 3 of the 6 play a sport. The teacher has collected data from all students and found that out of the 31 students in the class 21 of them played sports. Give the statistic for the...

5 part a) The business college computing center wants to determine the proportion of business students who have personal computers (PC's) at home. If the proportion exceeds 35%, then the lab will scale back a proposed enlargement of its facilities. Suppose 300 business students were randomly sampled and 85 have PC's at home. Find the rejection region for this test using α = 0.10. A) Reject H0 if z > 1.645 or z < -1.645. B) Reject H0 if z...
