Question

NASA is conducting an experiment to find out the fraction of people who black out at G forces greater than 6. Step 1 of 2 : Suppose a sample of 409 people is drawn. Of these people, 139 passed out at G forces greater than 6. Using the data, estimate the proportion of people who pass out at more than 6 Gs. Enter your answer as a fraction or a decimal number rounded to three decimal places.

Answer 1

The proportion of people who pass out at more than 6 Gs is 0.34.

Explanation:

In this sample, the proportion of people who pass out at more than 6Gs is the number of people in the sample who passed out at G forces greater than 6 divided by the size of sample

We have that:

Sample of 409 people is drawn. Of these people, 139 passed out at G forces greater than 6.

So the proportion is 139/409 = 0.34.
