A paper and pencil test of anxiety obtains a mean score of μ= 35 for all incoming freshmen. We want to determine whether the scores of a random sample of n = 25 new freshmen, with a mean score of M = 30 and a standard deviation of σ= 10, can be viewed as coming from this population. Does this sample of freshmen anxiety scores differ from the population of all incoming freshmen? Conduct the appropriate test using α = .05 and state your conclusion in terms of this problem.
