The following data (showing the number of hurricanes by category to directly strike the mainland U.S. each decade) obtained from www.nhc.noaa. gov/gifs/table6. gif 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 24 10 1951-1960 17 8 1961-1970 14 6 1971-1980 12 1981-1990 15 5 1991-2000 14 5 The correlation coefficient is -0.8549. Is this considered significant? Why or why not? O Yes, because -0.855 is inside the interval with the critical value endpoints of 10.811. O Yes, because -0.855 is outside the interval with the critical value endpoints of + 0.811. O No, because -0.855 is inside the interval with the critical value endpoints of 1 0.811. O No, because -0.855 is outside the interval with the critical value endpoints of + 0.811. QUESTION 5 The following data (showing the number of hurricanes by category to directly strike the mainland U.S. each decade) obtained from www.nhc.noaa.gov/gifs/table6. gif 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 24 10 1951-1960 17 8 1961-1970 14 6 1971-1980 12 4 1981-1990 15 5 1991-2000 14 5 2001 - 2004 9 3 Table 17 The data for 2001-2004 show 9 hurricanes have hit the mainland United States. The trend line predicts 2.72 major hurricanes to hit mainland U.S for 2001-2010. Can the trend line line be used to make this prediction? O No, because r is not significant even though the data shows a linear trend O Yes, because r is significant from the major hurricane data. Also the data shows a linear trend. O No, because the data seems not to be linear and r is not significant. O Yes, because how else could we predict what is going to happen this decade
