We reject H0 at level α of significance if and only if the p-value is: 2. Question : When carrying out a sample test (with ó known) of H0: µ = 10 vs. Ha: µ > 10 by using a rejection point, we reject Ho at level of significance a if and only if the calculated test statistic is 3. Question : When using the chi-square goodness of fit test, if the value of the chi-square statistic is large enough, we reject the null hypothesis. 4. Question : The actual counts in the cells of a contingency table are referred to as the expected cell frequencies. 5. Question : For a hypothesis test about a population mean or proportion, if the level of significance is less than the p-value, the null hypothesis is rejected. 6. Question : When we carry out a chi-square test for independence, the null hypothesis states that the two relevant classifications

6. Question : When we carry out a chi-square<br />

test for independence, the null hypothesis states that the two<br />

relevant classifications<br />

7. Question : The manager of the quality<br />

department for a tire manufacturing company wants to study the<br />

average tensile strength of rubber used in making a certain brand of<br />

radial tire. The population is normally distributed and the<br />

population standard deviation is known. She uses a Z test to test<br />

the null hypothesis that the mean tensile strength is less than or<br />

equal to 800 pounds per square inch. The calculated Z test Statistic<br />

is a positive value that leads to a p-value of .067 for the test. If the<br />

significance level is .10, the null hypothesis would be rejected.<br />

8. Question : A type II error is failing to reject<br />

a false null hypothesis.<br />

9. Question : For the chi-square goodness of fit<br />

test, the rejection point X2a is in<br />

10. Question : If a null hypothesis is not rejected<br />

at a significance level of .05, it will ______ be rejected at a<br />

significance level of .01.
