A test of hypotheses for one proportion has the following Null Hypothesis: pi = 0.33, and uses 0.10 for the level of significance.

a. If the calculated value for the associated test statistic equals -1.71, determine the p-VALUE for the test

0.0436

0.4564

0.2262

0.0872

b. If you compare the p-VALUE from Part a to the level of significance, what decision do you make?

Answer 1

Answer #1

a) z = -1.71

p-value = 2*(1-NORM.S.DIST(ABS(-1.71), 1)) = 0.0872

b) As p-value < 0.10, so we reject the null hypothesis.

Answer: Reject Null

Consider conducting a hypothesis test in which the null and alternative hypotheses are: Ho: ? ? c Ha: ? > c Where c is some hypothesized value. Suppose the significance level is 0.02, the test statistic is positive, and the statistical decision is to FTR Ho. If we redo the test at ? = 0.05, our statistical decision would be: ---Select--- There is not enough information to make a decision at 0.05 FTR Ho at ? = 0.05 Reject Ho at...
