d$.$ You can accomplish any one of the following at an additional cost of $$1,500.$ If you will save $$1,000$ for each day that the earliest completion time is reduced, which of the following actions should be taken, if any?

Reduce job $5$ by two days.

Yes

No $0$

Reduce job $3$ by two days.

Yes

No $0$

Reduce job $7$ by two days.

Yes

No $0$

e$.$ What is the probability that the project will take more than $30$ days to complete? $($Use Excel's NORMSDIST$()$ function to find the correct probability for your computed Z$-$value. Other than the expected completion time you entered in part $c$ above, do not round intermediate calculations. Round $"z"$ value to $2$ decimal places your final answer to $4$ decimal places.$)$
