A population has a mean of 200 and a standard deviation of 80. Suppose a sample of size 125 is selected and 39 is used to estimate 111.. Use z-table. a. What is the probability that the sample mean will be within +/- 7 of the population mean (to 4 decimals)? (Round 2 value in intermediate calculations to 2 decimal places.) 0.7416 0 b. What is the probability that the sample mean will be within +/- 10 of the population mean (to 4 decimals)? (Round 2 value in intermediate calculations to 2 decimal places.) 0.9198 0 TABLE 1 CUMULATIVE PROBABILITIES FOR THE STANDARD NORMAL DISTRIBUTION (Continued) Cumulative probability Entries in the table give the area under the curve to the left of the z value.
