A normal population has a mean of S91 and standard deviation of S10. You select random samples of 50, Required: a. Apply the central limit theorem to describe the sampling distribution of the sample mean with a 50 What condition is necessary to apply the central limit theorem? Applying the central limit theorem requires the population distribution to bo normal
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
