Answer:
The sample size must be atleast 502 to have a margin of error of 0.03
Step-by-step explanation:
We are given the following in the question:
Proportion = 0.32

Level of significance = 0.15
Margin of error = 0.03
Formula for margin of error =


We have to find the sample size such that the margin of error is atmost 0.03.
Putting values, we get,

Thus, the sample size must be atleast 502 to have a margin of error of 0.03 in approximation of proportion of people who would black out at 6 or more Gs.
