Exercise 8: Random Numbers

Part A:

Construct the following simple spreadsheet.

A B 1 0.52 =RAND()

Each time the spreadsheet recalculates, a new random number between 0 and 1 will appear in cell A2. (Hit F9, the recalculation key, to see for yourself.)

Modify the spreadsheet so that cell B2 says "higher" whenever the random number is greater than 0.5 and "lower" whenever the random number is less than 0.5.

Part B:

Construct the following simple spreadsheet.

A B 1 0.4 0.7 2 =RAND()

Modify this spreadsheet so that cell B2 says "higher" whenever the random number is greater than 0.7, "lower" whenever the random number is less than 0.4, and "in between" whenever the random number is between 0.4 and 0.7.
