Question 3
Question 3 of 15> It is believed that the height of the taller parent is related to the height of the tallest child. To test this, a random sample of 5 families were selected and the height of the tallest parent, to the nearest inch, and the height of the tallest adult child, to the nearest inch, were recorded. The results of the sample are listed in the table. 61 63 68 70 72 74 Height of tallest parent Height of tallest child 62 63 71 72 68 76 Which of the following is the value of the correlation between the height of the tallest parent and the height of the tallest adult child? O Cannot be determined because the height is not quantitative. O-0.790 O 0.790 O 0.889 O-0.889
