Question

(a) Determine if the relation between independent variable and dependent variable given below has a positive, negative or no correlation:

(i) The hours spent on studying and performance in an exam.
(ii) The wage earned with the working experience.
(iii) The number of computers at home with number of children.
(iv) The number of hours golfers practiced and their scores.
(v) Shoe size and height.

(b) Scores made by students in a statistics class in the midterm and final examination are
given below:

Student	Mid-term	Final
1	98	90
2	66	74
3	100	98
4	96	88
5	88	80
6	45	62
7	76	78
8	60	74
9	74	86
10	82	80

Develop a regression equation which may be used to predict final examination scores
from the mid-term score.

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.
