Given data:
Expected project completion time (μ) = 34 days
Standard deviation (σ) = 5 days
Time taken to complete the project (X) = 39 days
To find: Probability of completing the project in 39 days (P(X ≤ 39))

Formula:
We can use the standard normal distribution formula to find the probability.
z = (X - μ) / σ
where z is the standard normal variable.

From the formula, we get:
z = (39 - 34) / 5 = 1

Using the z-table or calculator, we find that the probability of z ≤ 1 is 0.8413.

Therefore, the probability of completing the project in 39 days is:
P(X ≤ 39) = P(z ≤ 1) = 0.8413

Hence, the correct option is (b) 0.84.
