Using the z-distribution, the test statistic is:
c) -2.63.
<h3>What are the hypothesis tested?</h3>At the null hypothesis we test if the means are equal, equivalent to a subtraction of 0, hence:
At the alternative hypothesis, we test if they are different, hence:
For each sample, they are given as follows:
.
.
For the distribution of differences, it is given by:
.
The test statistic is given by:
In which is the value tested at the null hypothesis.
Hence:
z = -2.63.
