Suppose that you want to set up a statistical test to challenge the claim of 7.6 seconds as the value obtained from the 50 car for a sample was 7.8. The standard deviation of the sample was .2. Use the significance level a=.01. a. State the Null and Alternate Hypothesis. b. Which test should be conducted in this scenario? c. Compute the numerical value of the test statistics. d. Find the p-value corresponding the test statistics. e. Is the test statistically significant? Will you reject or fail to reject the null hypothesis? f. Find the 95% Confidence Interval for the population.
