Question 23 Which scatterplot below depicts a stronger linear relationship 0.e. has the larger correlation coefficient)p O a. Scatterplot 1 shows a stronger linear relationship because it has more vertical variation among points. O b. Scatterplot 1 shows a stronger linear relationship because it has less vertical variation among points C. Scatterplot 2 shows a stronger linear relationship because it has more vertical variation among points. d. Scatterplot 2 shows a stronger linear relationship because it has less vertical variation among points.

Explanation / Answer

Question 23

Correct option : d. Scatterplot 2 shows a stronger linear realtionship becuase it has less vertical variation among points.

Reason : Less variation in scatterplot indicates better relationship among the variables.

Question 24

Correct option : d. the distribution of men's finish times is less variable than the distribution of women's finish times.

Reason : Standard deviation indicates the amount of variation in the distribution of observations.

Higher the standard deviation , more is the variation.

Question 25

Correct option : c. 0.72

Reason : Probability of an event occuring always lie between 0 and 1

Question 33
