A Paired t-Test reduces to the case of hypothesis test on a mean, variances unknown. A. True B. False

A. True

Step-by-step explanation:

A paired T- test is also sometimes called the dependent sample t-test. It may be defined as a statistical procedure that is mainly used to determine if the mean variance between the two samples or units of the observations are zero or not.

It helps to compare the two means which are taken from the same objects, related units or from same in individual.

According to the question, the answer is true as the paired T-test can be reduced to the single mean T- test.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
