Solution

In a scatterplot the response variable is shown on the vertical axis and explanatory variable on the horizontal axis.

if all data along a single line with a non zero slope then the value of r^2 is 1. (TRUE)

If the correlation between explanatory variable and response variable is zero, then the slope is also zero. (TRUE)

If the correlation between explanatory variable and the response variable is zero then it may be concluded that there is no association between them. (TRUE)

The use of linear equation to describe the association between price and sales implies that equal differences in sales when comparing periods with prices $10 and $11 and periods with prices $20 and $21. (TRUE)

A correlation of 0.8 implies that the two variables are strongly positively associated and a correlation of -0.8 implies that the two variables are strongly negatively associated.

The intercepts estimates how much the response changes on average with changes in the explanatory variable. (TRUE)
