In 2013, the Gallup Poll asked 1015 American adults whether they believed that people should pay sales tax on items purchased over the internet. Of these, 437 said they supported such a tax. Does the survey provide enough evidence that less than 45% of American adults favor an internet sales tax? Use α = 0.05 level of significance?
b) Step 2: Find the test statistic.
c) Step 3: P-value OR Critical value(s): Label answer as “P-value” or “CV” and draw a detailed curve.
d) Step 4: Decision
e) Step 5: Conclusion
f) What does the level of significance α = 0.05 means in hypothesis testing?

Greatest president ~ A Gallup Poll of 1800 American adults in
February 2009 asked the following question. "Which of the following
presidents would you regard as the greatest: Washington, Franklin
Roosevelt, Lincoln, Kennedy, or Reagan?" The order of the
presidents was rotated to avoid bias. Based on the sample, a 95%
confidence interval for the actual proportion American adults who
choose Lincoln as the greatest is given by (0.1122, 0.2211).Which
of the following statements are true? Select all the that...

A Gallup Poll asked a sample of Canadian adults if they thought
the law should allow doctors to end the life of a patient who is in
great pain and near death if the patient makes a request in
writing. The poll included 255 people in Quebec, 203 of whom agreed
that doctor-assisted suicide should be allowed.

A Gallup poll asked a sample of Canadian adults if they thought
the law should allow doctors to end the life of a patient who is in
great pain and near death if the patient makes a request in
writing. The poll included 295 people in Quebec, 230 of whom agreed
that doctor-assisted suicide should be allowed.

1) The Gallup Poll asked a random sample of 1785 adults whether
they attended church or synagogue during the past week. Of the
respondents, 44% said they did attend. Suppose that 40% of the
adult population actually went to church or synagogue last week.
Let p^ be the proportion of people in the sample who attended
church or synagogue. Find the probability of obtaining a sample of
1785 adults in which 44% or more say they attended church or
synagogue...

The Gallup Poll asked a probability sample of 2500 U.S. adults
whether they used a credit card to pay for groceries that week.
Suppose that 25% of the adult population did. We would like to know
the probability that an SRS of size 2500 would come within plus or
minus 2 percentage points of this true value.
If p-hat is the proportion of the sample who did use a credit
card to pay for groceries, what is the mean of...

said they were. Construct a 96% confidence interval to estimate the
proportion of national adults who are baseball fans. Use 4 non-zero
decimal places in your calculations.
a)Za/2

A 2003 Gallup poll asked 804 American adults who ate at fast
food restaurants at least monthly, if they would choose a healthier
menu option or stick with their current favorite item.
350 said they would choose a healthier menu option.
When the researchers report this result, what margin of error
should they state (for 95% confidence)?
lower limit = ____________________
Upper limit = ____________________
Margin of error = ± __________________________
(express as a decimal to 4 decimal places)
