Which of the following is NOT a criterion for making a decision in a hypothesis test?
Choose the correct answer below.
If the test statistic falls within the critical region, the decision is to reject the null hypothesis.
If
P-value,
the decision is to reject the null hypothesis. Otherwise, we fail to reject the null hypothesis.
If the P-value is less than 0.05, the decision is to reject the null hypothesis. Otherwise, we fail to reject the null hypothesis.
If a confidence interval does not include a claimed value of a population parameter, the decision is to reject the null hypothesis.

A hypothesis test is performed at the α = 0.05 level of significance. The p-value is determined to be 0.03. Therefore, we know that we would _______________. either reject or fail to reject the null hypothesis, depending on the value of the test statistic. reject the null hypothesis know that a 99% confidence interval would contain the value specified in the null hypothesis. fail to reject the null hypothesis

Is there a relationship between confidence intervals and two-tailed hypothesis tests? Let c be the level of confidence used to construct a confidence interval from sample data. Let α be the level of significance for a two-tailed hypothesis test. The following statement applies to hypothesis tests of the mean. For a two-tailed hypothesis test with level of significance α and null hypothesis H0: μ = k, we reject H0 whenever k falls outside the c = 1 − α confidence...
