Question

You want to make a confidence interval for the true average number of users of the video server at UF. A random sample of 8 days reveals the following numbers:

4593, 5197, 3865, 4835, 3900, 3171, 3559, 18091

Can we use the t table to make this confidence interval?

a) No, we should use the z table because the sample size is small.

b) No, since a plot of the data shows an outlier.

c) Yes, since the population is Normal.

d) Yes, because the sample is 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.
