Question
value 10.00 points Consider the following sample data: 7 25 9 y 580 309 145 52 9 18 6 b-1. Calculate the sample covariance. (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) Sample covariance b-2. Interpret the sample covariance. The covariance indicates that x and y have a positive linear relationship. The covariance indicates that x and y have a negative linear relationship. The covariance indicates that x and y have no linear relationship. c. Calculate the sample correlation coefficient. (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) Sample correlation coefficient eBook & Resources eBook: Conduct a hypothesis test for the population correlation coefficientExplanation / Answer
b 1) Using excel function COVARIANCE.S(), we get the covariance of 113.75
b2) Option A is Correct because covariance it is positive
b3) Using excel function CORREL(), we get the Sample Correlation coefficient of 0.06
