The time X taken by a randomly selected applicant for a mortgage to fill out a certain form has a normal distribution with µ = 10 minutes and σ = 2 minutes. (a) If five individuals fill out a form, what is the distribution of X¯, the average time taken by all five and find P(X <¯ 8). [2] (b) Suppose now that X is no longer normally distributed, but the mean and standard deviation are the same. However, 45 applicants fill the form. Answer the same questions as in a
