Without doing any computation, decide which has a higher probability, assuming each sample is from a population that is normally distributed with = 100 and = 15. Explain your reasoning. (a) P(90 x 110) for a random sample of size n = 10 (b) P(90sxs 110) for a random sample of size n = 20 Choose the correct answer below. OA. P(90 x 110) for a random sample of size n = 10 has a higher probability. As n increases, the standard deviation decreases. OB. P(90x110) for a random sample of size n = 10 has a higher probability. As n increases, the standard deviation increases. OC. P(90x110) for a random sample of size n = 20 has a higher probability. As n increases, the standard deviation decreases. OD. P(90x110) for a random sample of size n = 20 has a higher probability. As n increases, the standard deviation increases.
