Answer:
A quick comparison of the sample variances suggests that the population variances <u><em>are same or almost equal.</em></u>
Step-by-step explanation:
The populations from which two samples are drawn are normally distributed.
The variable used to predict another variable is called an independent variable.
F- distribution is used for the test of two sample hypotheses of variances.
If two populations have equal variances then the test Statistic is nearly equal to 1.
<em>t= s²₁/s²₂i</em>

As the variances are almost or nearly equal the test statistic would be almost equal to 1.
To get the value of n in the problem above, divide the sum by the number of n's added together. From the given, n + n = 24, there are only two n's added together. Hence, divided 24 by 2. The answer to this item is 12.
