16.What kind ofinformation is contained in the third box of information?(has Pooled and Satterthwaite in the left side ofbox)
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 ofVariances 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-sampleindependent 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 independentt-test output is used if the Equality of Variancep-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 independentt-test, are the population spreads for Bush andGore equal?
Select one:
a. No, because the S-W p-values for Bush andGore are both less than 0.05.
b. Yes, because we always assume equality of variances fortwo-sample, independent t-tests.
c. Yes, since the sample sizes for both Bush andGore is 50, which is greater than 30.
d. No, since the p-value in the Folded F rowis less than 0.05.
21.Looking at the output for the two-sampleindependent t-test, which p-value tests whetherthe mean number of votes for Bush and Gore areequal?
Select one:
a. 0.4563
b. 0.9124
c. 0.9125
d. 0.0309
