8)A student wonders if the number of hours a student studies for an exam is related to the score the student gets on the exam. She surveyed her classmates and made these observations:

The number of hours of study

10

12

14

16

18

The score obtained out of 100

60

70

80

90

92

a) Find the correlation r between the number of hours of study and the score obtained.

b) Use Table A-6 to find the critical values for r.

c) Determine if there is significant linear correlation in the population. Clearly state the conclusion.

Las question!!

For the paired data in problem 18 (hours of study Vs score):

1) Find the regression equation.

2)Find the best-predicted score when the number of study hours is 15

Need help on this please there is no missing data
