Use the accompanying paired data consisting of registered boats (tens of thousands) and manatee fatalities from boat encounters. Let x represent the number of registered boats and let y represent the corresponding number of manatee deaths. Use the given number of registered boats and the given confidence level to construct a prediction interval estimate of manatee deaths. Use x=84 (for 840,000 registered boats) with a 99% confidence level.Boats (tens of thousands)Manatees7153703764357047744070607954816885848579938095959472946798779992997210088929987819386878191759168Find the indicated prediction interval.nothing manatees<y<nothing manatees
Manatees are large, gentle, slow-moving creatures found along the coast of Florida. Many manatees are injured or killed by boats. below contains data on the number of boats registered in Florida (in thousands) and the number of manatees killed by boats for the years between 1977 and 2013.
