The 52 randomly selected history classes assigned an average of 19.4 pages of essay writing for the course. The standard deviation for these 52 classes was 3.3 pages. What can be concluded at the α = 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 dependent population means t-test for the difference between two independent population means z-test for a population proportion

1. The null and alternative hypotheses would be:   
2. The test statistic ? z t  =  (please show your answer to 3 decimal places.)
3. The p-value =  (Please show your answer to 4 decimal places.)
4. The p-value is ? > ≤  
5. Based on this, we should Select an answer reject fail to reject accept  the null hypothesis.
