Question

Listed below are the overhead widths (in cm) of seals measured from photographs and the weights (in kg) of the seals. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the critical values of r using

α=0.05.

Is there sufficient evidence to conclude that there is a linear correlation between overhead widths of seals from photographs and the weights of the seals?

Overhead Width	7.1	7.6	9.6	9.2	8.7	8.2
Weight	113	173	242	192	200	188

PLOTS INSERTED AS PICTURE

The linear correlation coefficient is

r=________.

(Round to three decimal places as needed.)

The critical values are

r=________.

(Round to three decimal places as needed. Use a comma to separate answers as needed.)

Because the absolute value of the linear correlation coefficient is

▼

less

greater

than the positive critical value, there

▼

is not

sufficient evidence to support the claim that there is a linear correlation between overhead widths of seals from photographs and the weights of the seals for a significance level of

α=0.05.
