Top Wealth Managers. An issue of HAKRON'S presented information on top wealth managers in the United States bused on individual clients with accounts of $1million er more. Data were given for various variables, two of which were a number of private client managers and private client assets. Those data are provided on the WeissStats site, where private client assets are in ballons of dollars.

a. Obtain a scatterplot for the dater.

h. Decide whether finding a depression lime for the data is reasonable. If so, then also do jurras (e) (f).

If there is no linear relationship between xand y, the variables are linear -------

Sample Covariance. For a set of n data points, the sample covariance, sxy+is given by

The sample covariance can be used as an alternative method for tinding the slope and y-intercept of a regression line. The formulas are

b1=sv/xk2andb0=y^-b1i^n

where sidenotes the sample standard deviation of the x-values.

a. Use Equation (4.1) to determine the sample covariance of the data points in Exercise 4,45.

b. Use Equation (4.2) and your answer from part (a) to find the regression equation. Compare your result to that found in Exercise 4.57.

Determine the linear correlation coefficient by formula and definition.

PCBs and Pelicans. The data on shell thickness and concentration of PCBs for 60Anacapa pelican eggs from Exercise 4.76 are on the WeissStats site.

a. decide whether use of the linear correlation coefficient as a descriptive measure for the data is appropriate. If so, then also do parts (b) and (c).

b. obtain the linear correlation coefficient.

c. interpret the value of r in terms of the linear relationship between the two variables in question.
