The following is a list of 14 measurements. -1, -38, -59, -12, −5, −77, −42, −50, −68, −62, −82, −9, −80, 42 Send data to calculator Suppose that these 14 measurements are respectively labeled x₁, x2, X₁4. (Thus, −1 is labeled x₁, -38 is labeled .x₂, and so on.) Compute the following. 14 Σ (*; -48) i=1 0 X

Eamine the computation formula for r, the sample correlation cofficient. (a) in the formula for r, t we exchange the symbols xand y, do we get a ciferert result or do we get the same (equivalent) result? Eplain your answer. O The resut is different because the formula is dependent on the symbois. O The resut is dimferent because the formula is not dependent on the symbols. O The resut is the same because the formula is dependent on the symbois. • The resut is the same because the formula is not dependent on the symbols. (b) we have a set of x and y data values and we exchange comesponding x and y values to get a new data set, should the sample comrelation coefficient be the same for both sets of cata? Explain your answer O The resut is the same because the formula is dependent on which values are the x values and which values are the y values. O The resut is different because the formua is not dependent on which values are the x values and which values are the y values. • The resut is…
