A one-sample Z-test was conducted to determine whether M105's average MSA score is the same as or different from B218's average MSA score of 19. A simple random sample of 44 students who took the M105 MSA was selected and its sample average was 17.2 marks. Assume that the standard error for M105's MSA score is 2.253. Write down the null and alternative hypotheses for the test. Determine the value of the sample z-statistic. Determine the p-value associated with the hypothesis test. Show clear explanation and workings.
