What will be an ideal response?
A t-test is a univariate hypothesis test using the t distribution, which is used when the standard deviation is unknown and the sample size is small. This test is based on Student's t statistic. The t statistic is a statistic that assumes that the variable has a symmetric bell-shaped distribution and the mean is known, and the population variance is estimated from the sample. The t distribution is a symmetric bell-shaped distribution that is useful for small sample testing.
