How do you use table A2 to compute z-distrubution probabilities?

Solution

1.Go to the row that represents the ones digit and the first digit after the decimal point (the tenths digit) of your z-value.

2.Go to the column that represents the second digit after the decimal point (the hundredths digit) of your z-value.

3.Intersect the row and column from Steps 1 and 2.

For example z=-1.92. The ones digit and the first digit after the decimal point (the tenths digit) of z-value is -1.9 and he second digit after the decimal point (the hundredths digit) of z-value is 2. so look at intersection of -1.9 and 0.02, that is 0.0274.
