relationship between happiness and number of pets owned for 57 people, based on a survey.
[CL1] Tips for problems 1-2: Recall that observational studies permit us to identify
relationships, but experiments must be conducted before we can make causal statements. Recall
from algebra that the slope of a linear equation indicates a rising (positive slope) or falling
(negative slope) line, in this way you classify plots of the data points by observing if the trend is
generally linear and rising or falling.
