Step-by-step explanation:
For checking the equivalence of two population variances of independent samples, we use the <em>f</em>-test.
The test statistic is given by:
It is provided that the hypothesis test is one-tailed.
The computed value of the test statistic is:
<em>F</em> = 4.23.
The degrees of freedom of the numerator and denominator are:
Use MS-Excel to compute the <em>p</em>-value as follows:
Step 1: Select function fX → F.DIST.RT.
Step 2: A dialog box will open. Enter the values of f-statistic and the two degrees of freedom.

Step 3: Press OK.
The <em>p</em>-value is, 0.0728.
The range of the <em>p</em>-value is:
0.050 < <em>p</em>-value < 0.100
