A statistician claims that the average score on a standardized test of students who major is psychology is greater than that of the average student. The results of the test, given to 70 pyschology students, had a sample mean of 85 with a sample standard deviation of 4. If the population average is 80, is there enough evidence to support the statistician's claim at a level of. significance of 0.025? (T-Test) Is the claim supported by this Hypothesis Test? A) There is no claim. B) The claim that the average.is 80 is supported by this Test. C) The claim that the average is greater than 80 foot is supported by the Test. D) The claim that the average is lower than 80 is supported by the Test.
