Apopulation has a mean of 200 and a standard deviation of 70. suppose a sample of size 100 is selected and is used to estimate . use z-table.
what is the probability that the sample mean will be within +/- 8 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 +/- 14 of the population mean (to 4 decimals)? (round z value in intermediate calculations to 2 decimal places.)
