A random sample of 788 subjects was asked to identify the day of the week that is best for quality family time. Consider the claim that the days of the week are selected with a uniform distribution so that all days have the same chance of being selected. The table below shows goodness-of-fit test results from the claim and data from the study. Test that claim using either the critical value method or the P-value method with an assumed significance level of a = 0.05. Num Categories 7 2990.946 Test statistic, x? Critical x2 P-Value 6 12.592 Degrees of freedom Expected Freq 112.5714 0.0000 Determine the null and alternative hypotheses. Ho: All days of the week have an equal chance of being selected. Hy: : At least one day of the week has a different chance of being selected. Identify the test statistic. x2 = (Type an integer or a decimal.)

A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 291 vinyl gloves, 62% leaked viruses. Among 291 latex gloves, 12% leaked viruses. Using the accompanying display of the technology results, and using a 0.10 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1. i Click the icon to view the technology results. What are the null and alternative hypotheses? A. Ho: P17 P2 Hy:P1 = P2 B. Ho: P1 P2 Hi: P1 = P2 C. Ho: P1>P2 H4:21 = P2 D. Ho: P1 = P2 H1:21 >p2 E. Ho: P1 = P2 H1: P17 P2 OF. Ho: P1 = P2 H1:21 <P2 Identify the test statistic. (Round to two decimal places as needed.)
