Suppose x has a distribution with = 12 and a = 6.USE SALT(a) If a random sample of size n = 41 is drawn, find , and P(12 sx s 14). (Round to two decimal places and the probability to four decimal places.)H-120.93XP(12 ≤ x ≤ 14)= 0.4842X(b) If a random sample of size n = 68 is drawn, find and P(12 sxs 14). (Round a to two decimal places and the probability to four decimal places.)H-12✓1.33xP(12 sxs 14)=0.4337X(c) Why should you expect the probability of part (b) to be higher than that of part (a)? (Hint: Consider the standard deviations in parts (a) and (b).)The standard deviation of part (b) is smaller than part (a) because of the larger ✔✔sample size. Therefore, the distribution about is wider✓x
