<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.

If a company has a bad reputation of allowing the sale of counterfeit goods, buyers will not trust the site and will not buy from it.
Answer:
Profit margin = net profit / total sales = $78 / $5,200 = 1.5%
Asset turnover = total sales / average total assets = $5,200 / ($2,990 + $3,510) = 1.6
Return on assets = net income / average total assets = $78 / $3,250 = 2.4%
Return on common stockholders’ equity = net income / average stockholders' equity = $78 / ($992 + $1,031) = 7.71%
Gross profit rate = gross profit / total sales = $1,716 / $5,200 = 33%
Eminem is best rapper and musicians
Answer:
$10,950 Unfavorable
Explanation:
For computation of flexible budget variance for total costs first we need to find out the standard cost which is shown below:-
Standard cost = (Sold connectors × budgeted variable costs) + Fixed costs per month
= (77 × $150) + $5,500
= $11,550 + $5,500
= $17,050
Flexible budget variance for total costs = Actual cost - Standard cost
= $28,000 - $17,050
= $10,950 Unfavorable
