Indicate whether the following statement is true or false. If we do not reject the null hypothesis, it is possible we have made both type I and type II errors. In an upper tail hypothesis test for the mean, the critical value is 2.575 and the test statistic is 2.5. In this case, the null hypothesis should not be rejected. The calculated p-value should be divided by 2 to make the decision for a two tail test. The sampling error...

In a two-tailed hypothesis test of the mean using a 0.05 level of significance, researchers calculated a p-value of 0.03. What conclusion can be drawn? The alternative hypothesis should be rejected because the p-value is so small. The null hypothesis is true because the p-value is less than the level of significance. The alternative hypothesis is 3% likely to be true. The null hypothesis should be rejected because the p-value is less than the level of significance. 1.The alternative hypothesis...

C. the null hypothesis will not be rejected unless the probability in the critical region is large. D. the null hypothesis will not be rejected unless the test statistic is larger (absolutely) than the critical value.
