Question

15.What kind of information is contained in the bottom box of information? (has Equality of Variances in the upper middle of box)

Select one:

a. Location information on the two populations.

b. Validity information on the hypothesis test.

c. Spread information on the two populations.

d. Descriptive information on the two samples.

16.What kind of information is contained in the third box of information? (has Pooled and Satterthwaite in the left side of box)

Select one:

a. Validity information on the hypothesis test.

b. Location information on the two populations.

c. Descriptive information on the two samples.

d. Spread information on the two populations.

17.What is the null hypothesis of Levene's Equality of Variances hypothesis test?

Select one:

a. H₀: The samples are equal.

b. H₀: The populations are equal.

c. H₀: The population variances are equal.

d. H₀: The population means are equal.

18.What is the null hypothesis of the two-sample independent t-test?

Select one:

a. H₀: The population means are equal.

b. H₀: The population variances are equal.

c. H₀: The samples are equal.

d. H₀: The populations are equal.

19.Which row of the two-sample independent t-test output is used if the Equality of Variance p-value = 0.08?

Select one:

a. The row for The Equal Variances.

b. The row for the Satterthwaite Method.

c. The row for the Pooled Method.

d. The row for the Folded F Method.

20.Looking at the output for the two-sample independent t-test, are the population spreads for Bush and Gore equal?

Select one:

a. No, because the S-W p-values for Bush and Gore are both less than 0.05.

b. Yes, because we always assume equality of variances for two-sample, independent t-tests.

c. Yes, since the sample sizes for both Bush and Gore is 50, which is greater than 30.

d. No, since the p-value in the Folded F row is less than 0.05.

21.Looking at the output for the two-sample independent t-test, which p-value tests whether the mean number of votes for Bush and Gore are equal?

Select one:

a. 0.4563

b. 0.9124

c. 0.9125

d. 0.0309
