ST512 - Lab 2 activities:

1) Inspect the code contained in the file "heights-lab2.sas"
2) Run the code 
3) Inspect the output that is generated

4) adapt the code to do the following tasks

4a) report the sample mean and sample variance for midparent 
    height and son height
4b) obtain 95% confidence limits for the slope
    of the regression line for the whole population.
4c) obtain 95% confidence limits for the MEAN height among
    sons with midparent height x=68
4d) obtain 95% confidence limits for the MEAN height among
    sons with midparent height x=70
4e) obtain 95% prediction limits for the height of an
    INDIVIDUAL son given his midparent height is x=70

(Which will be wider, the interval in 4c) or in 4d) ? )
(Which will be wider, the interval in 4d) or in 4e) ? )

4f) obtain the sample correlation coefficient for midparent
    heights and sons' heights
4g) obtain 95\% confidence limits for the population
    correlation coefficient for midparent and son height.

5) ask general questions about SAS
