Find the percentage of data points that lie between -2.31 and 1.85.

Step 1

Assuming the data follows standard normal distribution with mean 0 and standard Deviation 1

Finding the p-value at z = -2.31 = 0.010444 (From Excel = NORM.S.DIST(-2.31,TRUE)

Step 2

Finding the p-value at z = 1.85 = **0.967843** (From Excel = NORM.S.DIST(1.85,TRUE)

Step 3

Assuming the data follows standard normal distribution with mean 0 and standard Deviation 1

Finding the p-value at z = -2.31 = 0.010444 (From Excel = NORM.S.DIST(-2.31,TR...
