Question

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

Answer #1

Hope this will help you. Thank you :)

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...

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)...

According to the American Time Use Survey, adult Americans spend
a mean time of 2.35 hours a day watching television on a weekday.
Assume that the standard deviation for the time spent watching
television on a weekday is 1.93 hours.
a. If a sample of 40 adult Americans is obtained, describe the
sampling distribution of the mean x-bar. In other words, describe
the shape of the distribution, the mean of the sampling
distribution, and the standard deviation of the sampling...

The American Enterprise Institute (AEI) Public Opinion Study
found that 86% of Americans are satisfied with their job (AEI
website, December 4, 2015). Is this consistent across age groups? A
follow-up survey revealed that 72% of Americans age 18–30 are
satisfied with their job, 85% of Americans age 31–50 are satisfied
with their job, and 93% of Americans age 51–70 are satisfied with
their job. Suppose that 200 workers were surveyed in each age
group.
a.) Construct a 95% confidence...

From a national survey, it was found that about 37% of all
Americans have a short commute to work (i.e. the time it takes to
get to work is less than 15 minutes). suppose you randomly select 5
Americans.
(a). How many people would you expect to have a short
commute?
(b). What is the probability that all 5 people have short
commutes?
(c). What is the probability that at least one person does NOT
have a short commute?
(d)....

Let x be a random variable that represents the weights
in kilograms (kg) of healthy adult female deer (does) in December
in a national park. Then x has a distribution that is
approximately normal with mean μ = 69.0 kg and standard
deviation σ = 9.0 kg. Suppose a doe that weighs less than
60 kg is considered undernourished.
(a) What is the probability that a single doe captured (weighed
and released) at random in December is undernourished? (Round your...

The average height of an adult American woman is 64 inches.
Assume that σ= 3.1 inches. A sample of 39 adult American women was
taken. What is the probability that the x¯ was less than 65 inches
for this sample?
A. Can’t work this; normality of x¯ not
satisfied
B. 0.6265
C. 0.9780
D. 0.0220
