The probability that the mean price for a sample of 30 federal income tax returns is within $16 of the population mean is:
= 56%
Explanation:
a) Data and Calculations:
Population mean (preparation fee for 2017 federal income tax returns) = $273
Population standard deviation of preparation fees = $100
Mean price for a sample of 30 federal income tax returns = $257 (which is within $16 of the population mean)
z = (x-μ)/σ
z = standard score
x = observed value
μ = mean of the sample
σ = standard deviation of the sample
Z = ($273 - $257)/$100
= 0.16
Using the z-table
P = 0.5636
