Srh company claims that its employees at the analyst level earn an average of 500 per hour. T frac m a m b sqrt frac s 2 n a frac s 2 n b s 2 is an estimator of the common variance of the two samples.

Where.
Mathematically it is represented as t x μ s n. Once we know the value of t we can use statistical software or an online calculator to find the corresponding p value. The t statistic to test whether the means are different can be calculated as follows. Value of t 290 310 50 16 t value 1 60.
