Population 1 is Normally distributed with a mean of 40 and a standard deviation of 4, and population 2 is Normally distributed with a mean of 25
and a standard deviation of 7. Suppose we select independent SRSs of n1
= 100 and n2 = 85 from population 1 and 2 respectively. Which of the
following are the values of the mean and The standard deviation of the
sampling distribution of x1 - x2?*

Given f(x)= 9x+1 and g(x)=x^3, choose the expression (f*g)(x)
