A Gallup Poll showed that 44% of Americans are satisfied with the way things are going in the United States. Suppose a sample of 25 Americans are selected.
Find the probability that no less than 7 Americans are satisfied with the way things are going.
Find the probability that exactly 15 Americans are not satisfied with the way things are going.
Find the probability that the number of Americans who are satisfied with the way things are going differs by greater than 2 from the mean.
Find the probability that greater than 7 Americans are satisfied with the way things are going.
Find the probability that at least 15 Americans are not satisfied with the way things are going.
Find the probability that no more than 9 Americans are satisfied with the way things are going.
Find the probability that more than 40% but at most 65% of these Americans are satisfied with the way things are going.
Round to 4 decimals.

2. According to a Gallup poll conducted in 2008, 78.3% of
Americans felt satisfied with the way things were going in their
personal lives. A researcher wonders of the percentage satisfied is
lower today. To find out, the researcher surveys a random sample of
1,173 Americans, and finds that 895 feel satisfied with the way
things are going in their personal lives. The researcher wishes to
test the null hypothesis at a significance level of 0.05. (a)
Conduct a large...

A Gallup poll found that 493 of 1050 adult Americans believe it
is the responsibility of the federal government to make sure all
Americans have healthcare coverage. Construct and interpret a 90%
confidence interval for the proportion of adult americans who
believe it is the federal governments responsibility to make sure
all americans have coverage? What does this interval suggest?
According to a study, the proportion of people who are satisfied with the way things are...
According to a study, the proportion of people who are satisfied
with the way things are going in their lives is 0.76
Suppose that a random sample of 100 people is obtained. Complete
parts (a) through (e) below.
(a) Suppose the random sample of
100100
people is asked, "Are you satisfied with the way things are
going in your life?" Is the response to this question qualitative
or quantitative? Explain.
A.The response is qualitative because the responses can be
measured...

According to a Gallup Poll, 18% of Americans surveyed said that
they had gained “a lot” of weight in the past five years. Assume
that this result is true for the current population of Americans. A
random sample of 14 Americans is selected.
a.Find the probability that in a random sample of 14 Americans,
the number who will say they have gained “a lot” of weight in the
past five years is at most 2. Draw a distribution
b. Find...

A Gallup poll to survey the top concerns of Americans was
conducted. Suppose that 387 women and 359 men were independently
and randomly selected, and that 242 women and 202 men chose the
state of the economy as their biggest concern. Can we conclude that
the proportion of women (p1), choosing the state of the economy as
their biggest concern, exceeds the proportion of men
(p2)? Use a significance level of α=0.01 for the
test.
Step 1: Choose the correct alternative...

4. A 2012 Gallup poll surveyed Americans about their employment
status and whether or not they have diabetes. The survey results
indicated that 717 of the 47,774 employed (full or part time) and
146 of the 5,855 unemployed 18-29 year olds have diabetes. (a) If
you suspect that that having diabetes and being unemployed might be
related somehow, then what is the null and alternative
hypothesis?
(b) What is the pooled proportion?
(c) What is the standard error? (SE)
(d)...
