Question

When performing hypothesis tests,

options:

small P-values generally support the null hypothesis.

P-values are computed assuming the null hypothesis is correct.

a test statistic measures the difference between the data and what is expected if the null hypothesis is correct.

both (a) and (c) are true.

both (b) and (c) are true.

small P-values generally support the null hypothesis.

P-values are computed assuming the null hypothesis is correct.

a test statistic measures the difference between the data and what is expected if the null hypothesis is correct.

both (a) and (c) are true.

both (b) and (c) are true.

Explanation / Answer

When performing hypothesis tests,

a. False; small P-values generally support the null hypothesis. not true becase; P-value < level of siginificance ; reject the null hypothesis. So, small P-values ; reject the null hypothesis; so small P-vlaues does not support the null hypothesis.

b . True . P-values are computed assuming the null hypothesis is correct.

The P value, or calculated probability, is the probability of finding the observed, or more extreme, results when the null hypothesis (H0) of a study question is true.

c. True . a test statistic measures the difference between the data and what is expected if the null hypothesis is correct.

The test statistic compares your data with what is expected under the null hypothesis.

Both (b) and (c) are true.
