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...

Independent random samples of n = 100 observations each are drawn from normal populations. The parameters of these populations are: • Population 1: μ1 = 300 and σ1 = 60; • Population 2: μ2 = 290 and σ2 = 80. (1) What is the probability that the mean of Population 1 is between 294 and 306? (2) How many samples should be included if we want the probability in Part (1) to be at least 95%? (3) What is the...
