To test if two population means are the same.

Step-by-step explanation:

To Find :What is the purpose of a two sample t-test?

Solution:

Two sample test is used to check the difference between the two population means .

Let us suppose mean of population 2=

So, Two sample test is used to check whether or

Hence the purpose of a two sample t-test is To test if two population means are the same.

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested
