The population mean and standard deviation are given below. Find the required probability and determine whether the given sample mean would be considered unusual. For a sample of n=60, find the probability of a sample mean being less than 20.5 if u=21 and standard deviation =1.27. (Round to four decimal places as needed.)

1 1/7 hope i

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7

answer:

1.14285714286

step-by-step explanation:

divide 40 into 35 and you will get your answer

i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer

10+4√2 is the answer. i dont have the time to explain.
