In hypothesis testing, the hypothesis which is tentatively assumed to be true is called the

correct hypothesis

null hypothesis

alternative hypothesis

level of significance

When the null hypothesis has been true, but the sample information has resulted in the rejection of the null, a _________ has been made.

level of significance

Type II error

critical value

Type I error

The maximum probability of a Type I error that the decision maker will tolerate is called the

level of significance

critical value

decision value

probability value

A Type II error is the error of

accepting Ho when it is false

accepting Ho when it is true

rejecting Ho when it is false

rejecting Ho when it is true

For finding the p-value when the population standard deviation is unknown, if it is reasonable to assume that the population is normal, we use

the z distribution

the t distribution with n - 1 degrees of freedom

the t distribution with n + 1 degrees of freedom

none of the above

A hypothesis test in which rejection of the null hypothesis occurs for values of the point estimator in either tail of the sampling distribution is called

the null hypothesis

the alternative hypothesis

a one-tailed test

a two-tailed test

In hypothesis testing, the level of significance is

the probability of committing a Type II erro

the probability of committing a Type I error

the probability of either a Type I or Type II, depending on the hypothesis to be tested

none of the above

In hypothesis testing, b is

the probability of committing a Type II error

the probability of committing a Type I error

the probability of either a Type I or Type II, depending on the hypothesis to be tested

none of the above

When testing the following hypotheses at an a level of significance Ho: p £ 0.7 Ha: p > 0.7 The null hypothesis will be rejected if the test statistic Z is

z > za

z < za

z < -za

none of the above

Which of the following does not need to be known in order to compute the P-value?

knowledge of whether the test is one-tailed or two-tailed
