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:
3
Explanation:
Data provided in the question:
Sales for the last four months :
8, 10, 15, and 9 units
Last four forecast of sales:
9, 11, 8 and 12 units
Now,
The mean absolute deviation (MAD) value of these forecast will be calculated as:
MAD = [ ∑|Sales - Forecast sales| ] ÷ [ Total number of forecast ]
or
MAD = [ |8 - 9| + |10 - 11| + |15 - 8| + |9 - 12| ] ÷ 4
or
MAD = [ 1 + 1 + 7 + 3 ] ÷ 4
or
MAD = 12 ÷ 4
or
MAD = 3
