You devide $349.66 by is $116.55 and devide $365.00 by 3 is $121.06 so add $116.55 and $121.06 is about $237.61 each
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.

Hey!
~Set up the equation: -5(x-1)=40
~ Divide 5 on both sides: 40/-5
~ Simplify: x-1=-8
~ We want to get x by itself, so subtract +1 to both sides.
~ Simplify: x = -7
~ Therefore, x = -7.
