In a random sample of 25 subjects, the sample mean is found to be ´x=640, and the sample standard deviation is s=30. (a) (1 pt) Is this test for population proportion, mean or standard deviation? What distributionshould you apply for the critical value? The t distribution should be utilized since the population standard deviation is unknown. (b) (1 pt) Is the test a right-tailed, left-tailed or two-tailed test? The test would be left-tailed. (c) (2 pts) Find the test statistic. (Show work and round the answer to two decimal places)T = (640-650)/ (30/5) = -10/6 = -5/3 = -1.6667
