b. What is the standard error of the sampling distribution of sample means? (Round your answer to 2 decimal places.) Standard Error c. What is the probability that a sample mean is less than $90? (Round 2-value to 2 decimal places and final answer to 4 decimal places.) Probability
d. What is the probability that a sample mean is between $90 and $922 (Round z-value to 2 decimal places and final answer to 4 decimal places.) Probability e. What is the probability that a sample mean is between $92 and $93? (Round value to 2 decimal places and final answer to 4 decimal places.) Probability
f. What is the probability that the sampling error (P) would be $150 or less? (Round 2-value to 2 decimal places and final answer to 4 decimal places.) Probability
