In a Pew survey of American adults conducted between February-May of 2016, respondents were asked about race and racial issues; 84% of the 1,004 Black respondents reported that Blacks are treated less fairly than whites when dealing with police. Use this information to provide a 95% confidence interval for the proportion of Blacks in the US who believed that Blacks are treated less fairly than Whites when dealing with police between February-May of 2016?

A. Is the sample large enough to use formulas (is it large enough for the CLT to kick in)?

B. What is the standard error? Round to three digits.

sample proportions from a population with

proportion p = 0.45 for sample sizes of n = 50, n = 112, and n = 1100.

Round your answers to

three decimal places.

C. Calculate the 95% confidence interval for the proportion of Black people who think that Blacks are treated less fairly than Whites when dealing with police. Round to three digits.

D. Interpret the confidence interval in context.

E. Could we say that more than three-quarters (75%) of Blacks in the US between February-

May of 2016 believed that Blacks are treated less fairly than Whites when dealing with police? Why or why not? No hand written solution and no image
