A sample of 7 department store sizes (in thousands of square feet) and revenues (in millions 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?
Critical values = +0.754; there
sufficient evidence to conclude that there is a linear correlation between size and revenue of department stores.
0
Critical values = 10.875; there
sufficient evidence to conclude that there is a linear correlation between size and revenue of department stores.
0
Critical values = +0.875; there is not sufficient evidence to conclude that there is a linear correlation between size and revenue of department stores.
Critical values +0.754; there is not sufficient evidence to conclude that there is a linear correlation between size and revenue of department stores.
