A normal population has a mean of $64 and standard deviation of $16. You select random samples of nine

b. What is the standard error of the sampling distribution of sample means? (Round your answer to 2 decimal places.)

1. Standard Error = 5.33 CORRECT

c. What is the probability that a sample mean is greater than $67? (Round z value to 2 decimal places and final answer to 4 decimal places.)

1. Probability =

d. What is the probability that a sample mean is less than $60? (Round z value to 2 decimal places and final answer to 4 decimal places.)

1. Probability =

e. What is the probability that a sample mean is between $60 and $67?(Round z value to 2 decimal places and final answer to 4 decimal places.)

1. Prpbability =

f. What is the probability that the sampling error (x)

would be $9 or more? That is, what is the probability that the estimate of the population mean is less than $55 or more than $73? (Round z value to 2 decimal places and final answer to 4 decimal places.)

1. Probability =
