a) 51% of users of mobile phones use their phone at least once per hour,
It is a binomial distribution with n = 150, p = 0.51
mean = np = 150 multiply with 0.51 = 76.5
SD= sqrt(np(1-p) )= 6.1225
Since np and n(1-p) > 5, we can assume the distribution is normal.
B) please see the attached file.
c) It is a binomial distribution with n = 150, p = 0.02
mean = np = 150*0.02 = 3
SD= sqrt(np(1-p) )= 1.71464
Since np < 5, we cannot assume the distribution is normal.

Answer:
The marginal revenue = $2
Explanation:
Firstly we calculate the value in dollars for the number of boxes sold
For 100 boxes, we have 100 * 2 = $200
For 200 boxes, we have 200 * 2 = $400
Mathematically, the marginal revenue = (cost of 200 boxes- cost of 100 boxes)/difference in quantity
= (400-200)/(200-100) = 200/100 = $2
Thus affirms the fact that for a perfectly competitive firm, marginal revenue MR = P (price)
