6. Research Question: Is there a higher percentage of Christians among CSU students than among USC students?

To test this I set up the hypothesis test

H0 : pCSU = pUSC Ha : pCSU > pUSC

This test gave a p-value of 0.023.

(a) Give your conclusion in context for this test using α = 0.05. (Your conclusion should be written so that a lay person could understand.)

(b) Give your conclusion in context for this test using α = 0.01. (Your conclusion should be written so that a lay person could understand.)

(c) Using the same sample data as in the hypothesis test, would a 95% confidence interval for pCSU − pUSC include the value 0? Explain.

Suppose someone you know and their spouse has been trying to start a family for a couple of years. The wife thinks she may be pregnant, so there will be a pregnancy test. Suppose the test has the hypotheses

H0 : Wife is pregnant.

Ha : Wife is not pregnant. (

(d) What are the consequences of making a Type I error?

(e) What are the consequences of making a Type II error?

The council of higher education wants to compare the percentage of students that score A in two universities. In a random sample of 50 students from university one, 16 received a grade of A; and in a random sample of 40 students from university two, 8 received a grade of A. The 95% confidence interval for the difference in the proportion of students who received a grade of A is: a. -0.0638 to 0.3038 b. -0.0691 to 0.2983 c. 0.0365...

A history teacher believes that students in an afternoon class score higher than the students in a morning class. The results of a special exam are shown below. Can the teacher conclude that the afternoon students have a higher score? Use α = 0.01. Morning Students Afternoon Students n1 = 36 n2 = 41 x1= 83 x2 = 86 s1 = 5.8 s2 = 6.3 null hypothesis and t statistic , p value

ASU is concerned about the retention rate among its students, i.e. percentage of ASU students that return next semester.To do this, ASU randomly selects 200 students and records whether or not they return to ASU the following semester. What is the statistic? a. The percentage of the 200 students that returned. b. All ASU students. c. The percentage of all ASU students that returned. d. The 200 ASU students that were selected.

Researchers believe that a higher percentage of males are afflicted with cysturina than females. Suppose of the 50 individuals, 15 were females and the remainder were males. Using 99% confidence, estimate the proportion of females with cysturina. Then estimate the proportion of females afflicted with cysturina at 96% confidence.

You believe a higher percentage of students receive “passed advanced” in your school as opposed to a neighboring school. A random sample of 84 students from your school showed that 19 were pass advanced, and a random sample of 156 students from a neighboring school showed that 31 were pass advanced. If appropriate, test your hypothesis at the significance level .05. A: Are the assumptions met? B: State the hypotheses C:What is the test statistic? D: What is the p-value?...

Dan believes the success rate of students who take a morning class is higher than students who take an afternoon class in the same subject. In a morning class of 34 students, 30 have passing grades (C or better). In an afternoon class of 25 students, 18 have passing grades. What is H0: What is Ha: What is the p-value?

Research question: In the population of all Penn State students, are more than 80% enrolled full-time? In this question set you will be using StatKey to conduct randomization tests for a single proportion. These data are not built in to StatKey, so you will need to “Edit data” to enter in the sample counts. Please show screenshots and work. B. Using the five steps from the online notes, conduct a randomization test given that 350 students in a sample of...
