Suppose that an accounting firm does a study to determine the time needed to complete one person's tax forms. It randomly surveys 100people. The sample average is 22.7 hours. There is a known population standard deviation of 7.0 hours. The population distribution is assumed to be normal. x = σ = σ x = n = n − 1 = Which distribution should you use for this problem? (Round your answers to two decimal places.) X

Suppose baby kittens' weights are normally distributed with a mean of 11.4 and a standard deviation of 2.1. The Z-score tells you how many units above the average (if Z-score is positive) or below the average (if Z- Score is negative) any particular baby kitten's weight is. Find the baby kitten weight that corresponds to the following Z-scores. Use the formula Z where u is the mean, o is the standard deviation, and X is the baby kitten weight. a. Z = = 0.07, X = b.
