Repeat Exercise 9.61 with samples of size 50. In exercise 9.61 Independent random samples of 10 observations

Question:

Repeat Exercise 9.61 with samples of size 50.

In exercise 9.61

Independent random samples of 10 observations each are drawn from normal populations. The parameters of these populations are

Population 1: μ = 280, σ = 25

Population 2: μ = 270, σ = 30

Find the probability that the mean of sample 1 is greater than the mean of sample 2 by more than 25.
