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