Andru [333]

Answer:

The estimate of the proportion of people who pass out at more than 6 Gs is 0.279.

Number of people who passed out divided by the size of the sample.

We have that:

Sample of 502 people, 140 passed out at G forces greater than 6. So the estimate is:

p = \frac{140}{502} = 0.279

The estimate of the proportion of people who pass out at more than 6 Gs is 0.279.
