Answer:
one-sample t test
Explanation:
One-sample t-test: The given test compares a given sample of a defined population. The term 'defined population' refers to the parameter of the population which is known. It is often used to test the difference in the given population mean and the hypothesized value. Here, the actual population mean is referred with 'μ' and hypothesized mean with 'M'.
Example: The researcher uses the one-sample t-test when he wants to compare the sample mean to the actual population mean.
