There are two ways of ordering two letters and ; you can write the two orderings as and . (a) In an experiment, the outcome is an ordering of four letters , , , and . Define the sample space S by listing its elements in a way described above. (b) Describe an event where the letter comes last, by listing its elements. (c) Describe an event where the letter comes last and the letter does not come in the second place by listing its elements.

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). =
