Introduction to Confidence Intervals

Question 10 • CA-Statistics and Probability B

Does the confidence interval give evidence that e-books should be offered?

Answer
A
We cannot determine this without surveying all library patrons.
B
No, it is not reasonable to assume enough patrons might use the service because another 95% confidence interval might contain 0.75.
C
No, it is not reasonable to assume enough patrons might use the service because 0.75 is at the very top of the confidence interval.
D
Yes, it is reasonable to assume enough patrons might use the service because 0.75 is included within the confidence interval.
