Answers only Meteorologists have been recording the amount of rainfall in a certain region for several decades. The distribution of rainfall in the region is normally distributed with mean μ
= 110.4 centimeters and standard deviation σ
= 12.1 centimeters. The meteorologists frequently take simple random samples (SRS) of 21 different days and calculate the sample mean rainfall for the selected days.
For one of these samples, the sample mean was calculated to be x ̅
= 111.3. What is the z-score that corresponds to this sample mean?
(Round your answer to three decimal places.)
