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.
- n is the sample size.
The values of the parameters are given as follows:
.
The sample mean is:
Hence the test statistic is:
t = 0.7.

<h3>#SPJ1</h3>Answer:
The factor form is
Step-by-step explanation:
When it is required to factor the expression given in the problem, we have to first find a common term or terms, which will be found by either grouping the like terms or the splitting of the terms.
Now the expression that is given here is:
Now, here we will take:
Thus we will get:
Now we will do the middle term split as follows:
Substituting back , we will have:
Hence, the required factor form of the given expression will be:
