QUESTION:

The mortality rate from melanoma (skin cancer) during the 1950s was recorded for each of the 48 contiguous United States, plus Washington D.C. (as reported by Fisher, L.D. and van Belle, G. (1993). Biostatistics: A Methodology for the Health Sciences. John Wiley and Sons, New York, NY, p. 292).

In context, the negative relationship (shown in the scatterplot above) means that:

ANSWER:

The more southern the state, the higher the melanoma death rate.

Good job! From the scatterplot we see that the lower the latitude the higher the mortality per 10 million. In other words, the more southern the state, the higher the death rate. Note that since the response variable is the mortality per 10 million, it measures the death rate rather than the number of deaths.
