9.5 Practice Questions Exercise 09.36 (Population Proportion) 1. 2. Consider the following hypothesis test: Ho: p≥ 0.75 Ha: p < 0.75 A sample of 300 items was selected. Compute the p-value and state your conclusion for each of the following sample results. Use a = 0.05. Round your answers to four decimal places. a. p = 0.68 p-value Conclusion: p-value less than or equal to 0.05, reject Ho b. p = 0.72 p-value Conclusion: p-value greater than 0.05, do not reject ✓ Ho c. p = 0.70 p-value Conclusion: p-value less than or equal to 0.05, reject Ho d. p = 0.77 p-value Conclusion: p-value greater than 0.05, do not reject ✓ Ho Icon Key Question 1 01 2 ► Hint(s) Check My Work Hint(s) Check My Work
B. The test statistic, t=____ C.The P-value is_____ D.State the conclusion for the test. Reject the null hypothesis or Fail to reject the null hypothesis. E. Construct a confidence interval appropriate for the hypothesis test in part (a). ___lb<μ1−μ2<____lb F. Does the confidence interval support the conclusion found with the hypothesis test? (No/Yes) because the confidence interval contains (only negative values/ only positive values/ zero.)

Next question A golf association requires that golf balls have a diameter that is 1.68 inches. To deter hform to the standard, a random sample of golf balls was selected. Their diameters are shown in the accompanying data table. Do the golf balls conform to the standards? Use the x = 0.01 level of significance. Click the icon to view the data table. First determine the appropriate hypotheses. Ho: H₁: (Type integers or decimals. Do not round.) Find the test statistic. (Round to two decimal places as needed.) Find the P-value. (Round to three decimal places as needed.) What can be concluded from the hypothesis test? O A. Reject Ho. There is sufficient evidence to conclude that the golf balls do not conform to the association's standards at the α = 0.01 level of significance. B. Do not reject Ho. There is not sufficient evidence to conclude that the golf balls do not conform to the association's standards at the x = 0.01 level of significance. C. Do not reject Ho. There is sufficient…
