Data from 12 individuals was collected about their sleeping habits after meditation. These scores represent their sleep quality based on a 5 point Likert scale with higher numbers meaning better sleep quality. Use a μ = 2.4 SD = 0.75. Do these individuals differ in their sleep quality compared to the group average? Solve using the five steps of hypothesis testing. how to find Ho: M and HA: M (this is part of an assignment that can be completed as many times as necessary for 100% or whatever grade you choose, I'm just trying to understand how to do all of this because it's an online summer course and I'm very lost.
