Eva8 [605]

Answer:

The critical value of <em>F</em> is 3.55.

Step-by-step explanation:

The claim to be test is, the SAT scores for students entering two state universities may have different standard deviations. It is believed that the standard deviation at University A is greater than the standard deviation at University B.

The hypothesis for the test can be defined as:

<em>H₀</em>: The standard deviations are same, i.e. <em>σ</em>₁ = <em>σ</em>₂

<em>Hₐ</em>: The standard deviations are different, i.e. <em>σ</em>₁ > <em>σ</em>₂<em>.</em>

A <em>F</em>-test will be used to perform the hypothesis test.

The <em>F</em>-statistic is given by:

F=\frac{S_{1}^{2}}{S_{2}^{2}}\sim F_{\alpha/2, (n_{1}-1),(n_{2}-1)

The information provided is:

                                            University A University B

Sample mean                                   1104               1254

Sample Standard Deviation             134                108

Sample size                                      14                           8

Compute the critical value of F using MS-Excel as follows:

The degrees of freedom are:

df₁ = n₁ - 1 = 14 - 1 = 13

df₂ = n₂ - 1 = 8 - 1 = 7

<u>Step 1</u>:

Open function → F.INV.RT

A dialog box will open.

<u>Step 2</u>:

Enter the details as shown in the image below. Press OK

Thus, the critical value of <em>F</em> is 3.55.
