5. 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? (1 point)
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.
Critical values = ±0.754; there is sufficient evidence to conclude that there is a linear correlation between size and revenue of department stores.
