1.1nthis class wehave came across m1 quantities whose gig andmafl'tude canhe
interpreted sgpflatelg. What do each of the following mean? (a) Avalue has a ercore ul‘l (In) Avalue has 3 Lynne ofr2 (c) A 95% confidence interval for p11 7 p12 is (-0.15: 0.25) (d) A 95% eonfidmee intfl'val for “1 7 ptz is (015; (125) (e) A 95% confidence intm'val for .111 7 .112 is (-025; 4115) {1) Repeat parts (5) through (e): but now the 95% confidence interval is for p1 — 112
(g) The slope of the leastisquares regression equation ofy on x is 4,6 (h) The slope of the least-squares regression equation ofy on x is 4,6 Li) The residual fora given point is 037 (j) The residual fora given paint is -0.87 (k) In a multiple linear reyession equation predicting y from x1= 2:2: and X}: the slope corresponding tn X2 is 0,542,
(l) Ina multiple linear regression equation predicting y from x1_ x2; andxs; the slope corresponding to X: is 41542,

Top Answer

Part-f (c) As this confidence interval includes zero, so it means we are 95% confident that the proportions p1 and p2 are not... View the full answer
