Answer:
40000×1×9%=3 600 this is for year
60 is 25% of 240 and 12 is 24% of 50
25% is a fourth of 100%. So you want to find what number 60 is a fourth of. Multiply 60 by 4.
60x4=240
24% is 4.17th of 100%. Multiply 12 by 4.17
12x4.17=50

104
STEP-BY-STEP EXPLANATION:
Given:
Standard deviation (σ) = 700
Confidence level = 95%
Mean error (Eμ) = 135
We have for a confidence level of 95%:

Now, we calculate the minimum value of the sample size as follows:

The minimum sample size needed is 104
