Sample Question 1
When is a statistical procedure robust?

When sample is at least 20% of the population?

When it is used even though the sample is not SRS.

When confidence level or the P-value does not change very much even when the conditions are not fully met.

When the correlation between the test statistic and the P-value is close to 1.0 (or the correlation between the level of confidence and z* ic close to 1.).

Sample Question 2
In order to compare free-throw shooting skills of Deacons versus Teachers, 12 Deacons and 16 Teachers were randomly selected to test the hypotheses: Ho: μD=μT versus Ha: μD<μT . The results of the free-throw shooting skills test are: Two Sample T-test results (without pooled variances): μD=mean of Deacons μT=mean of Teachers Ho: μD-μT = 0 Ha: μD-μT < 0 Difference Sample Mean Std. Err. DF t-stat P-value μD-μT -7.31 4.2917 11 -1.5 0.081 On the basis of the P-value, what should we conclude at α=0.10?

The mean free-throw score for Teachers equals the mean for Deacons.

The mean free-throw score for Teachers is significantly less than the mean for Deacons.

The mean free-throw score for Deacons is significantly less than the mean for Teachers.

The mean free-throw score for Deacons is not significantly less than the mean for Teachers.
