Should the manager begin planning the swimming program before February 1? fill in the blank 76. If necessary, round your answer to two decimal places. Using the normal distribution, z = fill in the blank 77. If necessary, round your answer to two decimal places. If negative answer is required, enter the minus sign before the number.
