This distribution follows the normal distribution with a standard deviation of $32,000.a. If we select a random sample of 56 households, what is the standard error of the mean? (Round your answer to the nearest whole number.) Standard error of the mean b. What is the expected shape of the distribution of the sample mean? Sample mean (Click to select)Unknown. Not normal, the standard deviation is unknown. Normal. Uniformc. What is the likelihood of selecting a sample with a mean of at least $125,000? (Round z value to 2 decimal places and final answer to 4 decimal places.) Probability d. What is the likelihood of selecting a sample with a mean of more than $108,000? (Round z value to 2 decimal places and final answer to 4 decimal places.) Probability e. Find the likelihood of selecting a sample with a mean of more than $108,000 but less than $125,000.(Round z value to 2 decimal places and final answer to 4 decimal places.) Probability
