A
manufacturer of tennis rackets has designed a new racket and would
like to compare it to their previous design. The
company obtains
100 volunteer tennis players. Volunteers are randomly assigned to
one of two groups. Group 1 will use the company’s previous
design first and
then the new design. Group 2 will use the new design first and then
the previous design. Each player will serve 30 times with each
racket. The percentage of good serves with the two rackets will be
compared. The players are blinded to which racket they are using.
Also, the person recording the percentage of good serves is blinded
to which racket is being used. If the group of volunteers consists
of 60 professional tennis players and 40 beginners, how could the
experiment be improved? (5pts) (Paragraph answer at a
