What is t test?

A t-test is an inferential statistic that is used to see if there is a significant difference in the means of two groups that are related in some way. It's most commonly employed when data sets, such as those obtained by flipping a coin 100 times, are expected to follow a normal distribution and have unknown variances. A t-test is a hypothesis testing technique that enables for the testing of a population-based assumption.

How to solve?

formula used to caculate t test [tex]t=\frac{m-\mu}{s / \sqrt{n}}[/tex] where

t = Student's t-test

,m = mean

μ = theoretical value,

s = standard deviation

{n} = variable set size

hence t lies at 2.5% as we take only known values to conduct test.
