E) an F distribution
Sampling Distribution
The probability distribution of a given statistic based on a random sample, used to make inferences about the population.
Normal Distribution
A symmetric distribution in the shape of a bell, indicating that occurrences of data close to the mean are more common than those far from the mean.
Statistic
A statistic is a single measure of some attribute of a sample, used to infer or estimate the corresponding attribute in the population.
- Utilize the t-distribution to construct confidence intervals when the population standard deviation is not known and the sample size is small.
