Do political science classes require less writing than history classes? The 50 randomly selected political science classes assigned an average of 19.1 pages of essay writing for the course. The standard deviation for these 50 classes was 4.6 pages. The 52 randomly selected history classes assigned an average of 20 pages of essay writing for the course. The standard deviation for these 52 classes was 3.4 pages. What can be concluded at the αα = 0.10 level of significance? For this study, we should use Select an answer t-test for a population mean z-test for the difference between two population proportions t-test for the difference between two independent population means t-test for the difference between two dependent population means z-test for a population proportion The null and alternative hypotheses would be:        H0:  Select an answer μ1 p1 Select an answer > ≠ = < Select an answer μ2 p2     H1:  Select an answer μ1 p1 Select an answer ≠ > < = Select an answer p2 μ2 The test statistic ? t z = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.

The standard deviation for these 50 classes was 4.6 pages. The 52 randomly selected history classes assigned an average of 20 pages of essay writing for the course. The standard deviation for these 52 classes was 3.4 pages. What can be concluded at the αα = 0.10 level of significance?

For this study, we should use Select an answer t-test for a population mean z-test for the difference between two population proportions t-test for the difference between two independent population means t-test for the difference between two dependent population means z-test for a population proportion

  1. The null and alternative hypotheses would be:   
    2.   

 H0:  Select an answer μ1 p1 Select an answer > ≠ = < Select an answer μ2 p2   

 H1:  Select an answer μ1 p1 Select an answer ≠ > < = Select an answer p2 μ2

  1. The test statistic ? t z = (please show your answer to 3 decimal places.)
  2. The p-value = (Please show your answer to 4 decimal places.)
