A sample of 7 department store sizes (in thousands of square feet) and revenues (in millions of dollars) are found to have a linear coefficient of 0.445. Find the critical values for the linear correlation coefficient, assuming a 0.05 significance level. Is there sufficient evidence to conclude that there is a linear correlation between size
and revenue of department stores?
A-Critical values - 0.875; there is sufficient evidence to conclude that there is a linear correlation between size and revenue of department stores.
B-Critical values +0.754; there is sufficient evidence to conclude that there is a linear correlation between size and revenue of department stores.
C-Critical values = +0.875; there is not sufficient evidence to conclude that there is a linear correlation between size and revenue of department stores.
D-Critical values = +0.754; there is not sufficient evidence to conclude that there is a linear correlation between size and revenue of department stores.
