The students expected that as the number of attendances increases the GPA increases. a. [2 points] State Ho and Ha with regards to Bl: Ho: Ha: b. [2 points] The standard deviation of Y is 8. The square root of the sum of the squared residuals divided by n-Z equals 8 (note: the formula on slide 21 of Chapter 10). Does this suggest that the regression fits the data well? (No explanation required.) Circle one: Yes
