Many manatees are killed or injured by motorboats. Part of this table gives data on powerboat registrations (in thousands) and the number of manatees killed by boats in Florida in the years 1977 to 1991. Make a scatterplot of these data with powerboat registrations as the explanatory variable and the number of manatee deaths as the response variable (you do not have to turn in the scatterplot). 1977 447 13 1978 460 21 1979 481 24 1980 498 16 1981 513 24 1982 512 20 1983 526 15 1984 559 34 1985 585 33 1986 614 33 1987 645 39 1988 675 43 1989 711 50 1990 719 47 1991 716 53 a. (5 pts.) State and interpret the association for this scatterplot.
