![]() ![]() ![]() Take note, that the problem asks us to get the value to the RIGHT. The corresponding value is 0.8749, meaning it covers 0.8749 out of 1 of the curve to the LEFT. See the picture for the finding of the value. In this problem, the given z-score is 1.15, so using the z-table we must first look for 1.1 at the left-most column and then 0.05 at the top-most row. I have attached two pictures of z-tables that get the area to the LEFT. ![]() Take note, that some z-tables may give you the area to the LEFT or area to the RIGHT, always be mindful in checking that. This would be the corresponding area under the curve. Locate the first value at the left-most column and the second value on the top-most row and see where they meet in the table. A z-table allows us to determine the area under a standard distribution curve given the z-score.īreak up the z-score into the ones + tenths and hundredths place value. In order to determine this, it is mandatory to make use of the z-table. ![]()
