Answer:
-11,-1, square root of 5-13
Step-by-step explanation:
Using the t-distribution, the t-statistic for the two-sided test would be of t = 0.7.
<h3>What is the test statistic for a t-distribution hypotheses test?</h3>
The test statistic is given by:

The parameters are:
is the sample mean.
is the expected value.
- s is the standard deviation of the sample.
The values of the parameters are given as follows:
.
The sample mean is:

Hence the test statistic is:


t = 0.7.
