Perform the following steps in R. Answer the questions in parts where there are questions. Attach R code. (a) create a vector in R that contains the elements 10, 3, 6, 9, 20, 1, 4, and 5. (b) assign the vector to an R object named x. (c) assign x to another R object named y. Now you should have two stored R. objects, x and y. (d) print out x and y. Note that they are the same vector. (e) compute the variances for x and y. What are the variances for x and y? (f) compute the covariance between x and y. What is the covariance between x and y? (g) What is the relationship between the variance of x and the covariance between x and y? (h) compute the correlation between x and y. What is the correlation between x and

Perform the following steps in R. Answer the questions in parts where there
are questions. Attach R code.
(a) create a vector in R. that contains the elements 10, 3, 6, 9, 20, 1, 4, and 5.
(b) assign the vector to an R object named x.
(c) assign x to another R object named y. Now you should have two stored R objects,
x and y.
(d) print out x and y. Note that they are the same vector.
(e) compute the variances for x and y. What are the variances for x and y?
(f) compute the covariance between x and y. What is the covariance between x and y?
(g) What is the relationship between the variance of x and the covariance between x
and y?
(h) compute the correlation between x and y. What is the correlation between x and
y?
