Problem
Scenario
Does emotional intelligence vary based on the type of preschool a child attends? A researcher collects data on 300 four-year-olds who attend different local types of preschools. The researcher was able to collect data from four different types of preschools - Montessori, Waldorf, Parent Co-ops, and religious preschools. Emotional intelligence was quantified using the self-report Bar-On EQ-I, which ranges from 0 - 110, and is considered "scale" in nature. Assume data meets all assumptions for a parametric test.
Task
What is the null hypothesis for this scenario?
