The following data was calculated during a study on mortgage interest rates.Now find the critical value(s) and sketch the rejection region for this hypothesis test at a1%

significance level:

• The economistwould like to test the claim that the percent of thirty-year fixed-rate mortgage loans that have a4.75
• percent interest rateis less than22%
• .Sample size=40thirty-year fixed-rate mortgage loans
• Sample proportion=0.125

-Test statisticz0=1.45

Z0.10 Z0.05 Z0.025 Z0.01 Z0.005

1.282 1.645 1.960 2.326

Use the curve below to show your answer.

• Select the appropriate test by dragging the blue point to a right-, left- or two-tailed diagram.
• Then, set the critical value(s)using the purple slider on the right.
• Set the test statistic by dragging the point on the x-axis.

******Z=?

and is this a right, left, or two tailed test?

Are we failing to reject the Null Hypothesis or rejecting it?

Is there enough or not enough evidence to fulfill either of those options?
