Question

Chapter 6 Forum In the Healthy Hand-washing Survey conducted by Bradley Corporation, it was found that 64% of adult Americans operate the flusher of toilets in public restrooms with their foot. (a) Suppose a random sample of n = 12 adult Americans is obtained and the number x who flush public toilets with their foot is recorded. Explain why this is a binomial experiment. (b) What is the probability a exactly 8 adults flush public toilets with their foot? (c) What is the probability that fewer than 8 who flush public toilets with their foot? (d) What is the mean and the standard deviation of the binomial probability? You may use your TI 84 to answer the probability questions. However, state the formula used and how you use it.

Answer #1

In the Healthy Handwashing Survey conducted by Bradley
Corporation, it was found that 64% of adult Americans operate the
flusher of toilets in public restrooms with their foot. Suppose a
random sample of 20 adult Americans is obtained and the number who
flush public toilets with their foot is recorded.
Find the probability that exactly 12 flush public toilets with
their foot.
Find the probability that at least 16 flush public toilets with
their foot.
c. Would it be unusual...

In
the Healthy Handwashing Survey, it was found that 64% of adult
Americans operate the flusher of toilets in public restrooms with
their foot. Suppose you survey a random sample of 740 adult
American women.
a. Determine the probability that no less than 66% of those
surveyed flush toilets in public restrooms with their foot
b. What percentile does your answer in (a) represent

The center for disease control and prevention (CDC) recently
