Your company is considering submitting a bid on a major project. You determine that the expected completion time is 130 weeks an
Olenka [21]

Answer:

Option C) 146.5

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 130 weeks

Standard Deviation, σ = 10 weeks

We are given that the distribution of completion time is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(X<x) = 0.95

We have to find the value of x such that the probability is 0.95

P(X < x)  

P( X < x) = P( z < \displaystyle\frac{x - 130}{10})=0.95  

Calculation the value from standard normal z table, we have,  

P(z

\displaystyle\frac{x - 130}{10} = 1.645\\x = 146.45 \approx 146.5  

The project should be completed in 146.5 weeks or less.

Hence, 146.5 weeks should be set the due date such that there is a 95 percent chance that the project will be finished by this time.
