I need to create two excel workbooks

1.

In cell A1, find the probability that the z score is less than 1.27 when the mean is 0 and the standard deviation is 1.

Create the workbook and Save the completed worksheet as W5_6-1_Normal.xls

2.

In cell A1, find a z score corresponding to the 95 percentile when the mean is 0 and the standard deviation is 1.

Create the workbook and Save the completed worksheet as W5_6-1_ZScore.xls
