A baseball team claims that the mean length of its games is 1.6 hours. State H0 and Ha in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasoning. State the null hypothesis in words and in symbols. Choose the correct answer below. A. The null hypothesis expressed in words is, "the mean length of a baseball team's games is 1.6 hours." The null hypothesis is expressed symbolically as, "H0: μ=1.6." B. The null hypothesis expressed in words is, "the mean length of a baseball team's games is more than 1.6 hours." The null hypothesis is expressed symbolically as, "H0: μ≠1.6." C. The null hypothesis expressed in words is, "the mean length of a baseball team's games is at most 1.6 hours." The null hypothesis is expressed symbolically as, "H0: μ≤1.6." D. The null hypothesis expressed in words is, "the mean length of a baseball team's games is…

The table to the right includes results from polygraph experiments. In each case, it was known if the subject lied or not, so the table indicates when the polygraph test was correct. Use a 0.05 significance level to test the claim that whether a subject lies is independent of the polygraph test indication. Do the results suggest that polygraphs are effective in distinguishing between truths and lies? State the null and the alternative hypotheses. Choose the correct answer below. O A. Ho: The row and column variables are independent. H₂: The row and column variables are dependent. OB. Ho: At least one of the values is different from the others. Ha: All values in the table are equal. OC. Ho: All values in the table are equal. Ha: At least one of the values is different from the others.

In 2011, a U.S. Census report determined that 52% of college students are working students. A researcher thinks this percentage has changed and surveys 182 college students. The researcher reports that 106 of the 182 are working students. Is there evidence to support the researcher's claim at the 1% significance level? a. Determine the null and alternative hypotheses. Ho:p = H1: p ?V (Select the correct symbol and enter the value.) b. Determine the test statistic. Round to two decimal places. c. Find the p - value. Round to four decimal places. p- value = d. Are the results statistically significant? O Fail to reject the null hypothesis. O Reject the null hypothesis. e. Write the conclusion. O There is not sufficient evidence to support the claim that the percentage of working college students has changed. O There is sufficient evidence to support the claim that the percentage of working college students has changed.
