The closest to the minimum number of consumers needed to obtain the estimate with the desired precision is (b) 271
Explanation:
When the prior estimate of population proportion is not given , then the formula to find the sample size is given by :-
where E = Margin of error.
z* = Critical z-value.
As per given , we have
E = 5%=0.05
Confidence level = 90%
The critical value of z at 90% is 1.645 (By z-table)
Put all values in the formula , we get
n=0.25(1.645/0.05)²
n=0.25(32.9)²
n=270.6025≈271
Thus, the minimum sample size needed = 271
Hence , the correct answer is 271 .
Answer:
d. The price will stay the same, but the quantity will increase.

B. use existing transportation facilities.
C. minimize non-selling time.
D. determine duration of sales calls.
E. provide salespeople with an opportunity to plan their own routes and schedules
Answer:
Option C. Minimizing non-selling time.
Explanation:
The reason is that sales reps must lower their non selling time as this makes them inefficient for the company and would also increase their loss of time and commission. So every sales representative acknowledges his primary goal to decrease the non selling time which means he is trying to make sale.
