BUS 308 Week 4 Quiz
1.Question : Consider using p-value to test H0 versus Ha by setting a equal to .10. We reject H0 at level a 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
7.Question : The manager of the quality department for a tire manufacturing company wants to study the average tensile strength of rubber used in making a certain brand of radial tire. The population is normally distributed and the population standard deviation is known. She uses a Z test to test the null hypothesis that the mean tensile strength is less than or equal to 800 pounds per square inch. The calculated Z test Statistic is a positive value that leads to a p-value of .067 for the test. If the significance level is .10, the null hypothesis would be rejected.
8.Question : A type II error is failing to reject a false null hypothesis.
9.Question : For the chi-square goodness of fit test, the rejection point X2a is in
10.Question : If a null hypothesis is not rejected at a significance level of .05, it will ______ be rejected at a significance level of .01.
