Scenario 4: A researcher wants to study about the relationship between a students' grade in Mathematics and his average number of hours of sleep. Using the data from 23 families, the computed r between the grade and average number of hours of sleep was found to be 0.43. Test if there exists a significant relationship between the two variables at 1% level of significance. Interpret the computed r value. (Write your interpretation in statement form) Test if there is a significant relationship between the two variables at 5% level of significance. (Show complete proof/steps with conclusion in statement form)
