Answer: 0.59 ± 0.081 = (0.671, 0.509)  
Explanation: 
The sample proportion, p = 118/200 = 0.59 
The test statistic at 98% confidence interval is given by : 
p + z*Sqrt(p(1-p)/n) ; p - z*Sqrt(p(1-p)/n) 
z at 98% C.I. is 2.33 
Therefore, 0.59 + 2.33 * sqrt(0.59*(1-0.59)/200) and 0.59 + 2.33 * sqrt(0.59*
(1-0.59)/200)
 =0.59 + 0.081 and 0.59 - 0.081
 =0.671, 0.509

ch4aika [34]

Answer:

Temporary, Capital

polet [3.4K]

Answer:

Opportunity costs = 42,000 + 14,000 + 21,000 + 9,000 = $86,000

Explanation:

Opportunity cost is the cost of doing the next alternative.

In this case the opportunity cost would be the profits she has forgone and the costs she incurred to run the florist shop. Personal expenses are not included as we assume apartment and bill costs would be payable regardless of any decision.

Opportunity Costs = Next alternative + Costs of being a florist

Opportunity costs = 42,000 + 14,000 + 21,000 + 9,000 = $86,000

If Jacinda were making profits, we would subtract them from the salary that she could have earned.

Hope that helps.
