NASA is conducting an experiment to find out the fraction of people who black out at G forces greater than 66.

Step 1 of 2:

Suppose a sample of 595 people is drawn. Of these people, 303 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.

Step 2 of 2:
