The following data set contains the number of seats and the average flight-length for 17 aircraft. This data appeared in Contemporary Precalculus with Applications, by the North Carolina School of Science and Mathematics, published in 2000 by Everyday Learning Corporation, Chicago, IL. Flight Length (mi) Number of Seats 405 296 288 258 240 230 193 188 Aircraft 3,149 1,631 1,410 1,221 1,512 1,668 1,736 984 688 667 605 685 626 440 384 421 394 B747-100 L-1011-100/200 DC-10-10 A300 B4 A310-300 B767-300 B767-200 B757-200 ? 727-200 MD-80 B737-300 DC-9-50 B727-100 B737-100/200 F-100 148 142 131 122 115 112 103 102 78 DC-9-30 DC-9-10 A. Using your graphing calculator, construct a least-squares regression line for these data. B. Is the linear model appropriate for these data? Explain. C. State your hypotheses for a two-sided significance test of the slope of the regression line. D. Use your graphing calculator to find the test statistic and P-value for this significance test. E. Draw a conclusion based ont 9.9067 and p.0000000565 for the significance test H0 : ?1-0, Ha : A * 0 with ? .01. F. Calculate the standard error of the slope of the regression line. G. Construct a 99% confidence interval for the slope of the regression line. H. Interpret the confidence interval (5.32, 9.82) for the slope of the regression line.
