a. What is the probability that a sample of taxpayers from this income group who have itemized deductions will show a sample me within $192 of the population mean for each of the following sample sizes: 30, 50, 100, and 400? Round your answers to four decimals. n = 30 n = 50 n = 100 n = 400 b. What is the advantage of a larger sample size when attempting to estimate the population mean? Round your answers to four decimals. A larger sample - Select your answer - v the probability that the sample mean will be within a specified distance of the population mean. In this instance, the probability of being within ±192 of u ranges from for a sample of size 30 to for a sample of size 400.

a. What is the probability that a sample of taxpayers from this income group who have itemized deductions will show a sample me
within $192 of the population mean for each of the following sample sizes: 30, 50, 100, and 400? Round your answers to four
decimals.
n = 30
n = 50
n = 100
n = 400
b. What is the advantage of a larger sample size when attempting to estimate the population mean? Round your answers to four
decimals.
A larger sample -
Select your answer - v the probability that the sample mean will be within a specified distance of the population
mean. In this instance, the probability of being within ±192 of u ranges from
for a sample of size 30 to
for a
sample of size 400.
