Question 5 (20 marks) The following table has observations for 6 employees. Suppose that: X: The age in years. Y: The salary in hundreds. Use the following table to answer the question below. Given that: Mean of X=31 and standard deviation Sx=4 Mean of Y=14 and standard deviation Sy=5 X Y 31 11 28 10 3617 2612 23 7 40 25
2. Find the Coefficient of determination. Explain the result (is it a useful model)?
THE NORMAL DISTRIBUTION FUNCTION If Z has a normal distribution with mean 0 and variance I then, for each value of z, the table gives the value of 0(2), where 0(z) = P(Z
