A population has a mean of 300 and a standard deviation of 80.
Suppose a sample of size 125 is selected and is used to estimate.
Use *z*-table.

- What is the probability that the sample mean will be within +/-
4 of the population mean (to 4 decimals)? (Round
*z*value in intermediate calculations to 2 decimal places.)

- What is the probability that the sample mean will be within +/-
17 of the population mean (to 4 decimals)? (Round
*z*value in intermediate calculations to 2 decimal places.)
