What do we mean by critical values for significance in a hypothesis test for the population​ proportion? How does this compare to the critical values for statistical significance for a population​ mean? How do we use this for making decisions about the hypothesis​ test?

What do we mean by critical values for significance in a hypothesis test for the population​ proportion?

A. The critical values are the standard scores required for statistical significance at a given level.

B. The critical values are the values that correspond to the mean of the sample proportions.

C. The critical values are the probabilities required for statistical significance at a given level.

D. The critical values are the test statistics calculated for data sets.

How does this compare to the critical values for statistical significance for a population​ mean?

A. The critical values are from a uniform​ distribution, but those used with population means are from the normal distribution.

B. The critical values are similar to those used with population means but depend on the sample size.

C. The critical values are the same as those used with population means.

D. The critical values are similar to those used with population means but are from the binomial distribution.

How do we use this for making decisions about the hypothesis​ test?

A. The level of statistical significance is determined by calculating the test statistic using the critical values.

B. The level of statistical significance is determined by the number of standard deviations between the critical values.

C. The level of statistical significance is determined by comparing the standard score to the critical values.

D. The level of statistical significance is determined by comparing the level of significance to the critical values.
