a.)the theoretical probability of a head is 3/5.
b. )the experimental probability of a tail is 2/5.
c.) molly made an error, as she should have received 5 heads and 5 tails in her sample of 10 coin tosses.
d.) with more coin tosses, we would expect the number of heads to approach its experimental probability of 1/2.

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). =
