Question

he following data show the number of hurricanes to directly strike a certain country each decade. A major hurricane is one with a strength rating of 3, 4 or 5. Decade Total Number of Hurricanes Number of Major Hurricanes 1941 – 1950 21 12 1951 – 1960 17 9 1961 – 1970 13 6 1971 – 1980 12 4 1981 – 1990 15 5 1991 – 2000 14 5 2001 – 2004 9 3

Using only completed decades (1941 – 2000), calculate the least squares line for the number of major hurricanes expected based on the total number of hurricanes. (Round your answers to three decimal places.)

ŷ = +

Answer 1

THe regression analysis for the above data with 2001-2004 excluded is

number of major Hurricanes () = -6.775 + 0.887 *x

where x is number of hurricanes
