A school psychologist is interested in whether going to nature school, where children spend their day outside working with nature, versus public school has an effect on children's empathy toward their peers. A national survey of public schools found that, on a scale from 1 to 10, the average empathy among all children in public schools was 5 (u = 5.00). The school psychologist randomly selects 4 children from a nature school, measures their empathy toward their peers, and obtains the following scores: 10, 9, 10, 7 Using the appropriate hypothesis test and the six steps of hypothesis testing, see what the school psychologist should conclude about the difference in empathy between children who attend nature school versus children who attend public school. 1. What is the appropriate test to use ? 2. List the test's assumptions You do NOT have to test the assumptions. 3. What are the null and alternative hypotheses ? 4. Construct a sampling distribution of means representing the null…
