Mathematics
1 answer:
ZanzabumX [31]3 years ago
7 0
X² - 15 x + 36 = 0
x² - 12x - 3x + 36 = 0
x( x - 12) - 3( x - 12) = 0
(x - 3)( x - 12) = 0

x - 3 = 0
x = 3
or
x - 12 = 0
x = 12

The solutions are 3 and 12

Answer:

<em>F test</em>

Step-by-step explanation:

<em>For any test using the F-distribution, a "F Test" is a capture-all word. In certain circumstances, as individuals speak about the F-Test, it is the F-Test to compare two variances that they actually talk about. </em>

Moreover, in a multitude of tests, the f-statistics is used such as regression analysis, the Chow test and the Scheffe test (a post-hoc ANOVA test).

One should be using Excel, SPSS, Minitab or some other form of software to run the experiment if you are running a F test.

<em><u>Steps include.</u></em>

  1. State the hypothesis of nullity and the counter hypothesis.
  2. Determine the value of F. The F value is determined using equation F = (SSE1 – SSE2/m)/SSE2/n-k, where SSE = square residual, m = number of constraints, and k = number of independent variables.
  3. Find the statistics for F (the critical value for the test). The F statistical formula is: F Statistics = group mean / mean variance of variances within the group.  
  4. The F Statistics can be found in the F-Table.  
  5. The Null Hypothesis is accepted or denied.
