Is it more expensive to live in California or Florida? Monthly cost of living expenses for California are approximately Normal with mean C= $10,800 and standard deviation C = $3,200. Monthly cost of living expenses for Florida are approximately Normal with mean F = $8,500 and standard deviation F = $2,700. Suppose we select independent SRSs of 16 residents of California and 9 residents of Florida and calculate the sample mean monthly cost of living,xC and xF .
What is the shape of the sampling distribution of xC - xF ? Why?
