2. Suppose you wanted to determine whether or not there was a relationship between number of days spent training and reading comprehension on a scale, with higher scores meaning higher reading comprehension points. The data are as follows:

# of days spent training

X

6

7

3

8

5

Reading Comprehension on a Point Scale

Y

15

11

6

13

9

Let's say the correlation coefficient, r, is .77.

The Sx = 1.924 and Sy = 3.493.

The mean of x scores (days spent training) = 5.8

The mean of y scores (reading comprehension) = 10.8

Based on the above information, answer a - d below.

a.Calculate then interpret the slope based on the data and question above.

b.Calculate then interpret they intercept based on the data and question above.

c.Write out the unstandardized regression equation after calculating the slope and y intercept from the data above.

d.If someone spent 5 days training, what would you predict they would score on the reading task?
