A random sample of 77 eighth grade students scores on a national assessment has a mean score of 289.This test result promptly states a school administrator to declare the mean score for the states eighth grade exam is more than 280.Assume the population standard deviation is σ= 40. At α = 0.05, answer the following: a. State the null and alternate hypotheses (write it mathematically) and write your claim b. Find the test statistic. Find the p-value and interpret its meaning Identify the Rejection region (critical region) and fail to reject region by finding the critical value Decide whether to reject or fail to reject the null using the p-value approach Make an interpretation of your decision in the context of the claim.
