Find the critical value

t/α2

needed to construct a confidence interval of the given level with the given sample size. Round the answer to at least three decimal places.

Level 95%, sample size 9.

Critical value =

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.
