Large Sample Proportion Problem. Surveys were conducted in multiple countries and respondents were asked if they felt political news was reported fairly. The data for the United States is that out of 1,000 sampled, 470 indicated yes, they felt political news was reported fairly. Suppose we want to determine if the proportion for the U.S. is below .50 for an alpha level of .05.
What is conclusion of my test?
Group of answer choices
I would reject Ho: P=.5 because the test statistic is less than -1.645
I would fail to reject Ho: P=.5 because the p-value is greater than .05
I would reject Ho: P=.5 because the test statistic is greater than 1.645
I would fail to reject Ho: P=.5 because the test statistic is greater than -1.96

Large Sample Proportion
Problem. Surveys were conducted in multiple
countries and respondents were asked if they felt political news
was reported fairly. The data for the United States is that out of
1,000 sampled, 470 indicated yes, they felt political news was
reported fairly. Suppose we want to determine if the proportion for
the U.S. is below .50.
What is the standard error for this hypothesis test?
Group of answer choices
Cannot be determined from the information given.
SQRT((.5*.5)/1000)
SQRT((.47*.53)/1000
.4991/SQRT(1,000)

Imagine a poll is conducted with a large, representative sample
of US adults. Respondents are asked whether they think that the
influence of religion in the US is changing. They respond on a
scale from 0 to 10 where 0 means religion is becoming much less
influential, 5 means the influence of religion is not changing, and
10 means religion is becoming much more influential. The average
rating is 3.8 with a 2 point margin of error (95% confidence). The...

1. From a recent poll in which respondents were asked if they
felt that U.S. nuclear weapons made them feel safer, 550 out of
1000 people said “no.”
a) Find the sample proportion, ?̂, of people who responded “no”.
Use the appropriate formula and show your work.
b) Find the margin of error for a 95% confidence interval for
the true population proportion of people who feel that U.S. nuclear
weapons do not make them feel safer. Round to three...

Large Sample Proportion Problem. A survey was
conducted on high school marijuana use. Of the 2266 high school
students surveyed, 970 admitted to smoking marijuana at least
once. A study done 10 years earlier estimated that 45%
of the students had tried marijuana. We want to conduct a
hypothesis test to see if the true proportion of high school
students who tried marijuana is now less than 45%. Use
alpha = .01.
What is the conclusion for this test?
