Question

In hypothesis testing if the null hypothesis is rejected,

Group of answer choices

no conclusions can be drawn from the test

the alternative hypothesis is likely to be true

the data must have been accumulated incorrectly

the sample size has been too small

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
