Question

part 3 question 5

A college instructor wants to determine if there is a correlation between the performance in the final exam for students in his class, and the number of late submissions in their hw sets. The data is given below:

Grade on Final 65 88 60 45 92 78 85 63

Late hw submissions 4 3 8 10 2 1 7 10
1. Use α=0.05 to determine if there is a strong correlation between these variables.
2. What is the expected grade in the final for a student who has 6 late homework submissions?

Grade on Final	65	88	60	45	92	78	85	63
Late hw submissions	4	3	8	10	2	1	7	10

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
