Question

Use the following scenario to respond to items 11 - 12: A Pew Research Center Survey conducted in December 2017 reports that 32% of a sample of 4729 adults said they believe in a higher power or spiritual force in the universe other than the God of the Bible. Use the quick and approximate method to estimate the margin of error for a random sample of this size. Present your answer as a proportion rounded to 3 places after the decimal. Margin of Error = 0.015 QUESTION 12 Which of the following is (are) correct confidence intervals for this scenario? A. (31.985%, 32.015%) B. .015 $\pm$ 32 C. (0.305, 0.335) D. 1.5% $\pm$ 32% E. 32% $\pm$ 1.5% F. 32% $\pm$ .015%

suppose-this-was-a-survey-of-1175-randomly-selected-adults-in-the-united-states-what-is-the-approximate-margin-of-error-at-a-confidence-level-of-95-round-your-answer-as-percentage-to-one-dec-21086

Suppose this was a survey of 1175 randomly selected adults in the United States. What is the approximate margin of error at a confidence level of 95%? Round your answer as a percentage to one decimal place. Use your answer to question 4 to build a 95% confidence interval for the percentage of Americans in December 2015 who were very worried about terrorism. (Refer also to the top line of the table.) Write a 95% confidence interval statement that explains the meaning of this confidence interval in plain English, putting it in context. Suppose you wanted a margin of error of ±2 percentage points. According to the text, approximately what sample size would be needed for 95% confidence? (Use the same formula as in question 7, but you will know the margin of error and solve for the sample size.) Round your answer to the nearest whole number.

In a simple random sample of 1400 people age 20 and over in a certain country, the proportion with a certain disease was found to be 0.145 (or 14.5%). Complete parts (a) through (d) below. a. What is the standard error of the estimate of the proportion of all people in the country age 20 and over with the disease? SEest = (Round to four decimal places as needed.) b. Find the margin of error, using a 95% confidence level, for estimating this proportion. m = (Round to three decimal places as needed.) c. Report the 95% confidence interval for the proportion of all people in the country age 20 and over with the disease. The 95% confidence interval for the proportion is (,). (Round to three decimal places as needed.) d. According to a government agency, nationally, 13.6% of all people in the country age 20 or over have the disease. Does the confidence interval you found in part (c) support or refute this claim? Explain. The confidence interval this claim, since the value contained within the interval for the proportion. (Type an integer or a decimal. Do not round.) Enter your answer in each of the answer boxes.

00:01 All right, so with a sample size of 1175, we want to find the margin of error at a confidence level of 95%.
00:09 So 95 % confidence level results in z being 1 .96.
00:18 So our margin of error is going to be equivalent to z times the square root of p times 1 minus p over n.
00:34 So we're also going to have to assume that our p here is 0 .5 since it is not given.
00:38 So we're going to have 1 .96 times 0 .5 times 0 .5 over 1175.
00:49 So toss that into a calculator.
00:55 5, then 1175.
00:58 So we end up with a margin of error of 0 .0285.
01:07 So now we want to find n.
01:11 So this one was for 4.
01:13 This one's for 7...
