Question

An educator randomly assigns students to a program in which some will use new reading activities and others traditional teaching methods. At the​ end, both groups take a reading comprehension exam. Their scores are shown in the​ back-to-back stem-and-leaf display. Do these results suggest that the new activities are​ better? Test an appropriate hypothesis and state your conclusion. ​(Assume a significance level of α=0.05.)

Compute the​ t-statistic. t = ___________

​(Round to three decimal places as​ needed.)

Find the​ P-value. The​ P-value is ________

​(Type an integer or decimal rounded to four decimal places as​ needed.)

State the conclusion. Recall that α = 0.05

Choose the correct answer below.

1. Reject the null hypothesis. There is not sufficient evidence that the new activities are better
2. Reject the null hypothesis. There is not sufficient evidence that the new activities are better
3. Fail to reject the null hypothesis. There is sufficient evidence that the new activities are better
4. Fail to reject the null hypothesis. There is not sufficient evidence that the new activities are better
