Answer:

13 days

Explanation:

Calculation for the standard deviation for time using the beta statistical distribution

Expected time = [10 days + (4 * 12 days) + 20 days) / 6]

Expected time = [10 days + 48 days + 20 days) / 6]

Expected time=78 days/6

Expected time=13 days

Therefore the standard deviation for time using the beta statistical distribution is 13 days.
