Problems 6-10: In 2015 about 60% of college students used Twitter. In a recent study of 100 students, 80 now use Twitter. Is this evidence to think the percent has changed? We wish to conduct a hypothesis test with 5% significance.

6) State the null and alternative hypothesis.

7) Find the test statistic and P-value and report those values here:

8) What is the decision and conclusion?

9) Now, construct a 95% confidence interval using the sample of 100 students and 80 saying they use twitter.

10) Does the Confidence Interval support your decision for #8? Why or why not?

11 (Bonus): What type of error could we have made in this anaylsis? (Type 1 or Type 2)

From the given information in each case below, state what you know about the P-value for a chi-square test and give the conclusion for a significance level of α = 0.01. Use Table 8 in Appendix A. (Enter your answers to three decimal places.)

(a) χ2 = 4.98, df = 2

< P-value <

(b) χ2 = 12.18, df = 6

< P-value <

(c) χ2 = 21.06, df = 9

< P-value <

(d) χ2 = 20.7, df = 4

P-value <

(e) χ2 = 5.86, df = 3

P-value >
