Suppose that researcher A forms a twosided 95 percent confid

Suppose that researcher A forms a two-sided 95 percent confidence interval to estimate µ (the population mean). The result is L =.30 and U = .60. Researcher B, using the same data, performs a two-tailed hypothesis test of the null hypothesis µ = .45. Which of the following is true concerning the result of the hypothesis test?

Researcher B rejects the null hypothesis.

Researcher B fails to reject the null hypothesis.

Not enough information is given to know if researcher B rejects or fails to reject.

Researcher B will make a Type I error.

Solution

Researcher B fails to reject the null hypothesis.

The reason null hypothesis µ = .45 is inside the interval L =.30 and U = .60, & we fails to reject ho
