(4 points) 234S6 the strength of b) The correlation coefficient (r) of the above data is 994. Interpret the relationship between the number of x and y.

b)
The correlation coefficient between the two is 0.994 which means there is a strong positive correlation between the two variables. As the value of one variabe goes up, the value of other goes up as well.
c)
When the value of x is increased by 1, the value of y goes up by 2.03 keeping all other things constant.
d)
y=2.03x-2.32
y=2.03(16)-2.32
y=32.48-2.32
y=30.16
y=30 since 30.16 is less than 30.5
