Chris heard that if you bake a fair die at 200 degrees for 10 minutes, it will melt slightly on the inside, which shifts the weight to the bottom of the fair die and makes the die unfair. Chris did this for a fair die and would like to know if he succeeded in making an unfair die using α = 0.05. He rolls the die 120 times and obtains these counts: A 3-column table with 6 rows. Column 1 is labeled outcome with entries 1, 2, 3, 4, 5, 6. Column 2 is labeled observed with entries 11, 25, 20, 18, 15, 31. Column 3 is labeled expected with entries blank, blank, blank, blank, blank, blank.

If the die is fair, what is the expected count of each outcome?

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). =
