Consider the following sample information from Population A and Population B. Sample A Sample B n 24 16 s2 32 38 We want to test the hypothesis that the population variances are equal. The test statistic for this problem equals a. .84. b. .67. c. 1.50. d. 1.19.

Always the numerator for the statistic needs to be higher than the denominator. And replacing we got:

And the best option would be:

d. 1.19.

Step-by-step explanation:

Data given and notation  

represent the sampe size 1

represent the sample size 2

represent the sample variance for 1

represent the sample variance for 2

The statistic for this case is given by:

Hypothesis to verify

We want to test if the true deviations are equal, so the system of hypothesis are:

H0:

H1:

Always the numerator for the statistic needs to be higher than the denominator. And replacing we got:

And the best option would be:

d. 1.19.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
