Please answer this question.

a) The point estimate of (μ1−μ2) is? 

b) Calculate the value of the test statistic.
 
c) A 95% confidence interval to support this decision is _
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.
