Answer:
N = 3,120 (Approx)
Explanation:
Given:
z- score for 99% confidence = 2.58
Proportion (P) = 75% = 75 / 100 = 0.75
E = 2% = 0.02
Q = 1 - P = 1 - 0.75 = 0.25
Computation:





Therefore, N = 3,120 (Approx).
The total cost for this certain activity level can be calculated by substituting 4000 to the x of the equation given above,
y = 7000 + 1.8(4000)
y = 14200
Thus, the total cost of the activity level is $14,200.
