just need part d please The following is a record of Michael Jordan's remarkable basketball career up through 1998 (when he retired for the second time). SEASON AVERAGE POINTS PER GAME 1986-87 37.1 1987-88 35.0 1988-89 32.5 1989-90 33.6 1990-91 31.5 1991-92 30.1 1992-93 30.6 1995-96 30.4 1996-97 29.6 1997-98 28.7 A. Let 1985-86 be year 0. (Thus 1986-87 will be year 1, 1987-88 year 2 etc.) Draw a scattergram of this data below. B. Give the equation of the regression line. Then draw the regression line on the graph above. C. Use this regression equation to predict what Michael Jordan's average should be in 2002-2003. (His actual average was 20.0 points per game but your prediction may be very different.) D. How well does this regression line represent the data? Give reasons for your answer.
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.

A. Let 1985-86 be year 0. (Thus 1986-87 will be year 1, 1987-88 year
2 etc.)
Draw a scattergram of this data below.
B. Give the equation of the regression line. Then draw the regression line on
the graph above.
C. Use this regression equation to predict what Michael Jordan's average should be in 2002-2003. (His actual average was 20.0 points per game but your prediction may be very different.)
