Exercise 11-1 (Algo) (LO11-1) What is the critical F-value when the sample size for the numerator is five and the sample size for the denominator is eight? Use a two- tailed test and the 010 significance level. Note: Round your answer to 2 decimal places. Exercise 11-11 (Algo) (LO11-2) Do married and unmarried women spend the same amount of time per week using Facebook? A random sample of 45 married women who use Facebook spent an average of 9 hours per week on this social media website. A random sample of 39 unmarried women who regularly use Facebook spent an average of 9.4 hours per week. Assume that the weekly Facebook time for married women has a population standard deviation of 1.9 hours, and the population standard deviation for unmarried, regular Facebook users is 1.8 hours per week. Using the 0.01 significance level, do married and unmarried women differ in the amount of time per week spent on Facebook? Required: a. State the decision rule for 0.01 significance level: Ho : Hmen = Mwomen; H1 : Mmen # Mwomen . Note: Negative amounts should be indicated by a minus sign. Round your answers to 2 decimal places. Reject Ho if z b. Compute the test statistic. Note: Negative amounts should be indicated by a minus sign. Round your answer to 2 decimal places. The test statistic is z = c. What is the p-value? Note: Round your answer to 4 decimal places. p-value d. State your decision about the null hypothesis. Decision: null hypothesis.e. Do men and women differ in the amount of time spend on Facebook each day? Exercise 11-17 (Algo) (LON-3) Ms. Lisa Monnin is the budget director for Nexus Media Incorporated. She would like to compare the daily travel expenses for the sales staff and the audit staff. She collected the following sample information. Sales ($) 127 137 146 159 136 138 Audit ($) 122 13 127 136 149 126 142 Verify the assumption that the variances are equal. Use the 0.025 significance level. At the 0.025 significance level, can Lisa conclude that the mean daily expenses are greater for the sales staff than the audit staff? [#2pictureClick here for the Excel Data File Required: a.
