Here, report all answers to 4 decimal places. Use Daniel’s tables where applicable.

10. In a Gallup Poll of adults taken a number of years back, 40% of the respondents indicated that they had very little or no confidence in health maintenance organizations (USA Today, June 22, 2004). Assume that this is true for the current population (hope not!) of adults. Suppose a random sample of 16 adults is selected. Find the probability that the number of adults in this sample who have this opinion is:

a. at most 6

b. exactly 4

What if a sample of 120 patients were selected. Find the probability that the number of adults in this sample who have this opinion is:

c. at most 40

What if a sample of 4 patients were selected. Find the probability that the number of adults in this sample who have this opinion is:
