$4.(40$ points total$)$ The raw data in the file Frisbee.txt has two variables: $(1)$ Grip used to

throw the Frisbee disk $($finger out, normal, inverted$)$ and $(2)$ Distance of the disk$$s flight.

There is more than one observation per data line in the text file. You may paste the text

file into SAS data lines and create a data step that successfully reads all observations.

a$.(10$ points$)$ Use PROC UNIVARIATE to calculate statistics on distance of the disk$$s

flight separately for each grip.

b$.(10$ points$)$ Create side$-$by$-$side box plots to compare the grips. Create a custom title for

your output that gives a general description of the display.

c$.(10$ points$)$ Based on the above comparisons, which grip would you use to get the longest

flight? Explain in the context of your interpretation of the distribution of distances for

each grip. $($Place your response and explanation in a comment.$)$

d$.(10$ points$)$ Is there a grip that produces more consistency $($less variation$)?$ Explain. $($Place

your response and explanation in a comment.$)$
