Let S be the universal set, where: S = { 1 , 2 , 3 , ... , 28 , 29 , 30 } Let sets A and B be subsets of S , where: Set A = { 2 , 3 , 4 , 8 , 12 , 14 , 15 , 20 } Set B = { 1 , 2 , 6 , 7 , 8 , 19 , 22 , 27 , 28 , 29 } Find the number of elements in the set ( A ∪ B ) c n [ ( A ∪ B ) c ] =

Given are five observations for two variables, x and y. xi 1 2 3 4 5 yi 3 7 5 11 14 which of the following is a scatter diagrams accurately represents the data? what does the scatter diagram developed in part (a) indicate about the relationship between the two variables? try to approximate the relationship betwen x and y by drawing a straight line through the data. which of the following is a scatter diagrams accurately represents the data? develop the estimated regression equation by computing the values of b 0 and b 1 using equations (14.6) and (14.7) (to 1 decimal). = + x use the estimated regression equation to predict the value of y when x = 4 (to 1 decimal). =
