Using a t-distribution calculator, it is found that the critical value of the test statistic t is .
- The critical value is found using a calculator.
The inputs are:
- The tail.
- The amount of degrees of freedom, which is one less than the sample size.
- The significance level.
In this problem, we have a<u> lower(left-tailed) test, with 10 - 1 = 9 df and a level of significance of 0.1</u>, hence the critical value is .

<h2>Answer:</h2>
There is one/unique solution to the pair of equations for line A and line B.
<h2>Step-by-step explanation:</h2>We know that the equation of a line in slope intercept form is given by:
y= mx+b
where m is the slope of the line and b is the y-intercept of the line.
The <u>graph A:</u>
Line A has a slope of negative 1 and crosses the y axis at 5.
i.e. the slope of line i.e. m= -1
and y-intercept of line i.e. b=5
Hence, the equation of line A is:
y= -x+5
<u>Graph B:</u>
Line B has a slope of positive 1 and crosses the y axis at 3.
i.e. m=1
and b=3
Hence, the equation of line B is:
y=x+3
Now from the graph of these two lines we see that the system of lines intersect at just one point.
Hence, there is just one solution for the pair of equations.
