1.distribution is between z= 2.746 andz=2.746 (or within 2.746 standard deviations of the mean).

2.For the standard normal distribution, find:

P (0.1 < z < 2.41)

Round to 4 decimal places

3.Suppose your manager indicates that for a normally distributed data set you are analyzing, your company wants data points betweenz=1.5andz=1.5standard deviations of the mean (or within 1.5 standard deviations of the mean). What percent of the data points will fall in that range?

________% (Enter a number between 0 and 100, not 0 and 1 and round to 2 decimal places)

4.About __________________% of the area under the curve of the standard normal distribution is outside the intervalz= [1.83,1.83] (or beyond 1.83 standard deviations of the mean).
