For each problem, state the null and alternative hypotheses, calculate the teststatistic, determine the critical value or p-value (if applicable), and draw aconclusion based on the significance level a = 0.05. For subparts requestingconfidence intervals or confidence bounds, calculate them using a 95% confidencelevel. Also revise type 1 and type 2 error probabilities although not asked here.ProblemsProblem 1: A company claims that the mean weight of their cereal boxes isat least 500 grams. To investigate, you randomly select 30 cerealboxes and measure their weights. The sample mean weight is 495grams with a standard deviation of 10 grams.
