For testing the second figure in the report, let p be the proportion of email users who feel that spam has increased in their work email. The second set of hypotheses that the students wants to test, is then: Ho: p = 0.29 Ha: p ≠ 0.29 Based upon the data collected by this student, a 95% confidence interval for p was found to be: (0.273, 0.304). At the 0.05 significance level, which conclusion can be made? a. The student should not reject Ho, since 0.29 falls within the confidence interval. b. The student should reject Ho, since 0.29 falls within the confidence interval. c. The student should not reject Ho, since 0.29 does not fall within the confidence interval d. The student should reject Ho, since 0.29 does not fall within the confidence interval.
