a. Use a computer to generate your own abbreviated standard normal probability table (a short version of Table 3). Use z-values of 0.0 to 5.0 in intervals of 0.1.

b. How are the values obtained related to Table 3 entries? Make the necessary adjustment and store the results in a column.

c. Compare your results in part b with the first column of Table 3. Comment on any differences you see.
