of graduation.

(a) What is the shape of the sampling distribution of? Justify.

(b) What are the mean and standard deviation of the sampling distribution of?

(c) Interpret the standard deviation of the sampling distribution of.

(d) The admissions office finds that only 30% of the 350 graduates in the SRS had full time employment within one month of graduation.Assuming the university's claim that 35% will have employment is true, find the probability that 30% or less of a sample of 300 have full time employment.

(e) Does the admissions office have convincing evidence that the proportion of graduates who have full time employment within one month of graduating is actually lower than 35%?Justify.
