Explain what "statistical significance" means. Choose the correct explanation below. O A. Statistical significance means that the tools used to measure the data introduce error that needs to be accounted for when considering whether or not to reject the null hypothesis. O B. Statistical significance means that the sample standard deviation is unusually small, resulting in an unusually large test statistic. O C. Statistical significance means that the result observed in a sample is unusual when the null hypothesis is assumed to be true. O D. Statistical significance means that the null hypothesis claims the population proportion is equal to something other than 0.5. O E. Statistical significance means that the scenario being analyzed will have a meaningful real-world impact.

The average starting salary of students who graduated from colleges of Business in 2009 was $48,800. A sample of 100 graduates of 2010 showed an average starting salary of $50,000. Assume the standard deviation of the population is known to be $7000. We want to determine whether or not there has been a significant increase in the starting salaries. a. State the null and alternative hypotheses to be tested. b. Compute the test statistic. c. The null hypothesis is to be tested at the 5% level of significance. Determine the critical value for this test. d. What do you conclude from the test? e. What does the test result mean in the context of this problem?
