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 alpha=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?

Construct a scatterplot. Choose the correct graph below.
The linear correlation coefficient r is
(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
is
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 alpha=0.05

Listed below are the log body weights and log brain weights of
the primates species in the data set ”mammals”. Find the equation
of the least squares line with y = log brain weight and x = log
body weight. Do it by hand, by constructing a table like the one in
Example 9.1. Then do it with your calculator as efficiently as
possible. Finally, use the lm function in R to do it by creating a
linear model object...

1. Listed below are the temperatures from nine males measured at
8 AM and again at 12 AM.
(a) Construct a scatter plot.
(b) Find the coefficient of correlation and corresponding p
value.
(c) Based on the graph, does there appear to be a relationship
between 8 AM temperatures and 12 AM temperatures? How significant
is this relationship? State the null hypothesis and accept or
reject it. Give your reason for the decision.

Fifty-four wild bears were anesthetized, and then their weights
and chest sizes were measured and listed in a data set. Results are
shown in the accompanying display. Is there sufficient evidence to
support the claim that there is a linear correlation between the
weights of bears and their chest sizes? When measuring an
anesthetized bear, is it easier to measure chest size thanweight?
If so, does it appear that a measured chest size can be used to
predict the weight?...
