Question

For each part, select the best response.

For the population of patients suffering from a particular disease, a 95% confidence interval for ?μ, the population mean systolic blood pressure, is 95 to 105 dollars.

(a) The confidence interval would tend to refute the claim that the population mean systolic blood pressure of patients is __________.

A. more than 110
B. more than 80
C. at least 80
D. less than 100
E. at most 97

(b) The confidence interval provides no strong evidence to support or refute the claim that the population mean systolic blood pressure of patients is __________.

A. more than 97
B. at least 120
C. less than 110
D. at most 110
E. more than 90

Answer 1

The 95% confidence interval for the population mean $\mu$ is (95, 110)

(a)The confidence interval would tend to refute the claim that the population mean systolic blood pressure of patients is- A. more than 110

(As the confidence interval does not contain values more than 110 , so it will refute this claim)

(b) The confidence interval provides no strong evidence to support or refute the claim that the population mean systolic blood pressure of patients is-B. at least 120

( AS the confidence interval contains values that are less than 120)
