# please answer the following ATTACHMENT PREVIEW Download attachment Screen Shot 2019-10-14 at 10.54.12 PM.png Suppose x has a distribution with [.1 = 11 and a = 5. (a) If a random sample of size n = 37 is drawn, find )1}, or; and P(11 S )7 s 13). (Round 0; to two decimal places and the probability to four decimal places.) #;= 0;: P(11 525 13) = (b) If a random sample of size n = 69 is drawn, ﬁnd u}, a; and P(11 S )7 S 13). (Round 0; to two decimal places and the probability to four decimal places.) #;= 0;: P(11 525 13) = (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 ---Select--- a part (a) because of the ---Select--- a sample size. Therefore, the distribution about ,u; is ---Select--- a .

a) E(xbar) = 11.00 SD(Xbar) = 0.82 P(11 &lt; X &lt;... View the full answer
