Properties of scaling. Suppose that you want to examine the relationship between wages and experience measured in months rather than years. a) What is the variance of experience in months? Compare this to 1b). b) What is the covariance of wages and experience in months? Compare this to 1d). c) What is the correlation of experience and wages? Compare this to le). d) Prove mathematically that the Corr(cX,Y) = Corr(X,Y) using the properties of summation from class. Show each step of your proof.
e=D33 A traffic officer is compiling information about the relationship between the hour of the day and the speed over the limit at which the motorist is ticketed. He computes a correlation coefficient of 0.12. What does this tell the officer? Select one: O a. There is a quadratic relationship between the variables O b. There is a strong positive linear correlation. O c. There is a strong negative linear correlation. O d. There is little evidence of a linear correlation.

Answer.
(c) Are your estimates in parts (a) and (b) upper and lower estimates? Ex- plain. (A) (b) is a lower estimate and (a) is an upper estimate since v is a decreasing function of t. (B) (a) is a lower estimate and (b) is an upper estimate since v is an increasing function of t. (C) (a) and (b) are neither lower nor upper estimates since v is neither an increasing nor decreasing function of t. (d) Let's find an overestimate and underestimate of the distance traveled by the motorcycle during this time period.

Hi. PLease note I already asked this question and received the wrong answer. Jobs and productivity! How do retail stores rate? One way to answer this question is to examine annual profits per employee. The following data give annual profits per employee (in units of 1 thousand dollars per employee) for companies in retail sales. Assume σ ≈ 3.6 thousand dollars. 3.9 6.5 4.5 8.7 7.5 5.2 8.3 5.9 2.6 2.9 8.1 −1.9 11.9 8.2 6.4 4.7 5.5 4.8 3.0 4.3 −6.0 1.5 2.9 4.8 −1.7 9.4 5.5 5.8 4.7 6.2 15.0 4.1 3.7 5.1 4.2 (a) Use a calculator or appropriate computer software to find x for the preceding data.
