The Comrades committee decided to investigate the age (in years) of male and female runners. The descriptive statistics obtained from the two independent samples are recorded in the table below. Male runners Female runners Sample Size = 15 n = 12 Sample Mean = 31.6 Zz = 35.17 Sample Standard S1 = 5.026 $2 = 6.847 Deviation Research question: The Comrades committee would like to investigate whether the average age of male and female runners differ significantly from each other at an a = 0.05 level of significance. Let: 41 = average age of male Comrades runners H2 = average age of female Comrades runners Given: The age of the male and female runners are normally distributed with unequal variances. Under the null hypothesis, the test statistic has at distribution with 19 degrees of freedom, i.e.t to.
