Solution:
X follows Uniform(a = 65 , b = 88)
PDF of X is
f(x) = 1/(b - a) = 1/(88 - 65) = 1/23
Now ,
P(exceeded 70)
= P(X > 70)
= (b - 70)/(b - a)
= (88 - 70)/(88 - 65)
= 18/23
= 0.7826

2. Determine the water evaporation for the month of August for a reservoir using the data from the attached table. (Hint: Determine the monthly average values first, then use the average monthly values in the model to determine the evaporation for the month. Do not use missing data when calculating average values.) Assume a short vegetation height (0.1 feet) over the reservoir when using the wind model. [Answer: e =0.621 in Hg; ed =0.506 in Hg; Evaporation=2.18 inches for the...
