Extracted text: Ho: H20 Consider the following hypothesis test: A sample of 50 provided a sample mean of 19.4. The population standard deviation is2 a. Compute the value of the test statistic. b. What is the p-value? c. Using a .05, what is your conclusion? d. What is the rejection rule using the critical value? What is your conclusion? Ho: μ245 Consider the following hypothesis test A sample of 36 is used. Identify the p-value and state your conclusion for each of the following sample results Use α .01 a. x 44 and s 5.2 b. x 43 and s 4.6 C. x 46 and s 5.0 Ten years ago 53% of American families owned stocks or stock funds. Sample data collected by the Investment Company Institute indicate that the percentage is now 46% (The Wall Street Journal, October 5, 2012) Develop appropriate hypotheses such that rejection of H o will support the conclusion that a smaller proportion of American families own stocks or stock funds in 2012 than 10 years ago. Assume that the Investment Company Institute sampled 300 American families to estimate the percent owning stocks or stock funds was 46% in 2012. what is the p-value for your hypothesis test? a. b. c. Ata .01, what is your conclusion? Chapter 14 Look at handouts I gave you on Friday, April 26th & examples we went over in class.
