(a) State the appropriate null and alternate hypotheses and what kind of tail it has (right, left, or two)

(b) Compute the P-value and test statistic

(c) State a conclusion. Use the given level of significance.

Part 6 of 7 (f) Following is a boxplot of the data. Explain why it is not reasonable to assume that the population is approximately normally distributed. X X 200 250 300 350 400 It is not reasonable to assume normality because of skewness skewness X 5 outliers sample size(D) Perform a hypothesis test to determine whether you can conclude that the mean score in 2019 differs from the mean score in 2018. Assume the population standard deviation is o = 118. Use the a = 0.05 level of significance and the P-value method with the TI-84 Plus calculator. State the null and alternate hypotheses.
