Do government employees take longer coffee breaks than private sector workers? That is a question that interested a management consultant. To examine the issue, he took a random sample of 11 government employees ("govt" = sample/population1) and another random sample of 11 private sector workers ("privt" = sample/population2) and measured the amount of time (in minutes) they spent in coffee breaks during the day.

Is there sufficient evidence to support the consultant's claim? 1. The hypothesis for testing this claim? 2. Assuming equal population variances, the decision rule at the 5% level of significance is? 3. The calculated test statistic for this test is 4. The conclusion at the 5% level of significance is (assuming equal variances): 5. Assuming unequal population variances, the decision rule at the 1% level of significance is 6. The p value for this test, assuming unequal variances at the 1% level of significance, is 7. The conclusion at the 1% level of significance is (assuming unequal variances)
