Let the sample size of leg strengths be 7 and the sample mean and sample standard deviation be 630 watts and 32 watts, respectively. (a) is there evidence that leg strength exceeds 600 watts at significance level 0.05? find the p-value. there is choose your answer; there is _ evidence that the leg strength exceeds 600 watts at alpha = 0.05 evidence that the leg strength exceeds 600 watts at choose your answer; p-value, lower bound < p-value < choose your answer; p-value, upper bound (b) compute the power of the test if the true strength is 610 watts. round your answer to four decimal places (e. g. 98.7654) d = enter your answer; d round your answer to one decimal place (e. g. 98.7) the power of the test is enter your answer; the power of the test is (c) what sample size would be required to detect a true mean of 610 watts if the power of the test should be at least 0.9? n = choose your answer in accordance to the item c) of the question statement
