**Title: Understanding Undergraduate GPAs Through Normal Distribution****Description:**The undergraduate grade point averages (UGPA) of students taking an admissions test in a recent year can be approximated by a normal distribution, as shown in the figure.**Questions:**(a) What is the minimum UGPA that would still place a student in the top 5% of UGPAs?(b) Between what two values does the middle 50% of the UGPAs lie?**Graph Explanation:**The graph is a normal distribution curve representing the UGPAs. Key details are:- **Mean (μ):** 3.32- **Standard Deviation (σ):** 0.21- **X-axis:** Represents the grade point average.- The graph shows a symmetrical bell curve centered at a mean UGPA of 3.32.**Additional Information:**(a) The minimum UGPA that would still place a student in the top 5% of UGPAs is [box for answer].**Note to Students:**Use this information to understand how GPA distributions can influence admissions outcomes and to calculate critical cutoff points using statistical methods.

GSS 2018 respondents were asked to rate their level of agreement to the statement, “Differences in income in America are too large.” Responses were measured on a 5-point scale: 1 = strongly agree, 2 = agree, 3 = neutral, 4 = disagree, and 5 = strongly disagree. Strong Democrats had an average score of 1.69 (s = 1.04, N = 86) while strong Republicans had an average score of 2.11 (s = 1.05, N = 67). The estimated standard error of the difference between meansis 0.17. What is the appropriate test statistic? Why? Test the null hypothesis with a one-tailed test (strong Democrats are more likely to agree with the statement than strong Republicans); α = .05. What do you conclude about the difference in attitudes for these two political groups? If you conducted a two-tailed test with α = .05, would your decision have been different?
