Which of the following correlation coefficients indicates sufficient evidence of linear correlation? Select one: a. r = 0.9 b. r = 0 c. r = 0.09 d. r = 9
Answer: Option a) r = 0.9
The correlation coefficient r = 0.9 indicates that there is very straong linear positive ralationship between the two variables.
Where as r = 0 shows there is no linear relationship exist between two variables.
r = 0.09 shows that there is very low linear relationship between the two variables.
and the correlation coefficent r =9 is not correct because the range of correlation coefficient is -1 to 1.

Is there sufficient evidence to support a claim of linear correlation? Yes or No The Minitab output shown below was obtained by using paired data consisting of weights (in lb) of 29 cars and their highway fuel consumption amounts (in mi/gal). Along with the paired sample data, Minitab was also given a car weight of 3000 lb to be used for predicting the highway fuel consumption amount. Use the information provided in the display to determine the value of the...
