A manager wants to test whether two normally distributed and independent populations have equal variances. the appropriate test statistic for this test is a "F-statistics."
<h3>
What is F-statistics?</h3>
An F statistic is a value obtained after performing an ANOVA test or even a regression analysis to determine whether the means of two populations differ significantly.
Some key features regarding the F-statistics are-
- It is comparable to a T statistic from the a T-Test; a T-test would then inform you when a single result is statistically significant, whereas a F test would then tell you if a set of variables is statistically significant.
- When determining whether your total results are significant, you must use the F statistic in conjunction with the p value. Why?
- A significant result does not imply that all of your variables have been significant.
- The statistic is simply comparing the cumulative influence of all the variables.

The value of x will be2.217 and PR will be 13.085 units.
<h3>What is a line segment?</h3>
A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
Given that,
Line PQ consists of two segments PR and RQ
So,
PQ = PR + RQ
17 = 5x+2 + x² - 1
x² + 5x - 16 = 0
The roots of the equation will be
x = [-5 + √(25 + 64) ] ÷ 2
x = 2.217
Now,
PR = 5(2.217) + 2 = 13.085
Hence "The value of x will be2.217 and PR will be 13.085 units".
