Question

(a) Use the given information to find the sampling error: 𝑥̅ = 9.5, 𝜇 = 8.76, 𝑛 = 35, 𝑠 = .35, 𝑐 = .9

(b) Which of the confidence levels will produce the widest interval.

(c) In a survey of 1002 U.S. adults, 752 say they recycle. Find the point estimate for p.

Answer 1

The sampling error is the difference between the sample mean (9.5) and the population mean (8.76).

The higher the confidence level, the wider the confidence interval.

The point estimate for p is 752/1002.
