Records of 50 used passenger cars and 50 used pickup trucks were randomly selected to investigate whether there was any difference in the mean time in years that they were kept by the original owner before being sold. For cars the mean was 3.3 years with standard deviation 1.2 years. For pickup trucks the mean was 5.5 years with standard deviation 3.0 years. *Note: Assume the population mean to be 2 years a. State the null and alternate hypothesis in words and symbols (0.50 points) b. Mention the type of test (i.e. one tailed or two tailed) (0.15 points) (*Note :Use 90% confidence level) c. Compute the z-statistic (1.5 points) d. Compute the critical value (0.35 points) e. Compute the p-value(0.25 points) f. State the final conclusion in words (0.25points) g. Calculate the power for the above z-test with an effect size of 0.33 (1 points) *Note: make sure you look up the parameters for the power function and set the right value for the "alternative" parameter. The documentation of the power function should provide you with that information. Use the '?' symbol followed by the function name to access the documentation right from R studio or you could google it as well
