The living space for homes in a neighborhood of north Peoria has an approximately normal distribution with a population mean of 2200 square feet and a population standard deviation of 300 square feet. What is the probability that a random sample of 25 homes would result in a sample mean of less than 2000 square feet? [ Hint: We are talking about the mean of the sampling distribution of the sample mean.] Select one: a. 0.0400 b. 0.0004 c. 0.0040 d. 0.3330

I know that the sum of square of normal random variables follow a chi-square distribution. But when I learn how to do a goodness-fit test I don't know why the ratio of (O-E)^2/E follows a chi-square. I tried to square root of it first so that I might get something looks like a normal, but my new question arises : why (O-E)/sqrt(E) follows a normal-distribution? I know from sampling distribution that if the sample is from the same distribution as...
