Question

The accompanying table lists the ages of acting award winners matched by the years in which the awards were won. Construct a​ scatterplot, find the value of the linear correlation coefficient​ r, and find the​ P-value of r. Determine whether there is sufficient evidence to support a claim of linear correlation between the two variables. Should we expect that there would be a​ correlation? Use a significance level of

alphaαequals=0.050.05.

Construct a scatterplot. Choose the correct graph below.

A.

20702070Best Actress (years)Best Actor (years)

A scatterplot has a horizontal axis labeled Best Actress in years from 20 to 70 in increments of 5 and a vertical axis labeled Best Actor in years from 20 to 70 in increments of 5. Twelve points are plotted with approximate coordinates as follows: (22, 56); (28, 44); (30, 40); (30, 54); (30, 36); (32, 48); (32, 48); (46, 44); (44, 58); (58, 34); (62, 44); (64, 38).Your answer is correct.

B.

A scatterplot has a horizontal axis labeled Best Actress in years from 20 to 70 in increments of 5 and a vertical axis labeled Best Actor in years from 20 to 70 in increments of 5. Twelve points are plotted with approximate coordinates as follows: (68, 34); (62, 48); (60, 50); (60, 38); (60, 56); (58, 44); (58, 42); (44, 48); (46, 34); (32, 56); (28, 48); (26, 54).

C.

20702070Best Actress (years)Best Actor (years)

A scatterplot has a horizontal axis labeled Best Actress in years from 20 to 70 in increments of 5 and a vertical axis labeled Best Actor in years from 20 to 70 in increments of 5. Twelve points are plotted with approximate coordinates as follows: (68, 56); (62, 44); (60, 40); (60, 54); (60, 36); (58, 48); (58, 48); (44, 44); (46, 58); (32, 34); (28, 44); (26, 38).

D.

20702070Best Actress (years)Best Actor (years)

A scatterplot has a horizontal axis labeled Best Actress in years from 20 to 70 in increments of 5 and a vertical axis labeled Best Actor in years from 20 to 70 in increments of 5. Twelve points are plotted with approximate coordinates as follows: (22, 34); (28, 48); (30, 50); (30, 38); (30, 56); (32, 44); (32, 42); (46, 48); (44, 34); (58, 56); (62, 48); (64, 54).The linear correlation coefficient r is

nothing.

Answer 1

On X-axis Best Actress

On Y-axis Best Actor

A scatter plot has a horizontal axis labeled Best Actress in years from 20 to 70 in increments of 5 and a vertical axis labeled Best Actor in years from 20 to 70 in increments of 5. Twelve points are plotted with approximate coordinates as follows: (22, 56); (28, 44); (30, 40); (30, 54); (30, 36); (32, 48); (32, 48); (46, 44); (44, 58); (58, 34); (62, 44); (64, 38).
