<u>Solution and Explanation:</u>
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: All of the Above
Explanation:

Answer:
False
Explanation:
Whenever, there will be reduced production costs, due to any reason in the economy, then the goods will be cheaper and accordingly the sale will be in abundance assuming other factors remain constant.
Thus, due to subsidies the cost to producers will be less and then exporters will not be able to get more share as domestic goods will cost cheaper.
Thus, there will not be any gain to foreign competitors in our domestic markets, as they will not get any share extra rather they will loose as a foreign competitor. In fact goods which are exported will also cost low, and therefore, will gain new customers.
Therefore, above stated statement is false.

Answer:
$14,960
Explanation:
Pay $22,000 bill in December:
$22,000 tax deduction × 32%marginal tax rate = $7,040 in present value tax savings.
After-tax cost= Pretax Cost − Present Value
Tax Savings= $22,00 − $7,040
= $14,960
Therefore the after-tax cost if she pays the $22,000 bill in December will be $14,960
