Given the population mean, μ = 45, and the population standard
deviation, σ = 15 with a sample size of, n = 100.n = 100. Determine
P ( x ¯ ≤ 42 ). To do this problem first determine the sampling
mean and the sampling standard deviation in order to convert to a
z-score. Round your answer to 4 decimals.

Suppose that we have the data from 10 subjects and they reported
their ages as the following: 19, 24, 31, 31, 54, 34, 62, 22, 45,
27. What is the standard deviation of this sample? (Round to two
decimal places)

The average score on the MA 170 final is 76 and the standard
deviation is 8. Estimate the score that would put you in the top
10%. Round to the nearest whole number.
