here as we can see that Y=1000*X
therefore E(Y)=1000*E(X)=52.5*1000 =52500
and SD(Y)=SD(1000*X)=1000*SD(X) =1000*12.5=12500

Let x represent the average annual salary of college and university professors (in thousands of dollars) in the United States. For all colleges and universities in the United States, the population variance of x is approximately σ2 = 47.1. However, a random sample of 20 colleges and universities in Kansas showed that x has a sample variance s2 = 86.8. Use a 5% level of significance to test the claim that the variance for colleges and universities in Kansas is...
