Question
Skating A figure skater tried various approaches to her
Salchow jump in a designed experiment using 5 different
places for her focus (arms, free leg, midsection, takeoff
leg, and free). She tried each jump 6 times in random
order, using two of her skating partners to judge the jumps
on a scale from 0 to 6. After collecting the data and ana-
lyzing the results, she reports that the F-ratio is 7.43.
lyzing the results, she reports that the F-ratio is 7.43.
a) What are the null and alternative hypotheses?
b) How many degrees of freedom does the treatment
sum of squares have? How about the error sum of
squares?
c) Assuming that the conditions are satisfied, what is the
P-value? What would you conclude?
d) What else about the data would you like to see in order
to check the assumptions and conditions?
b) How many degrees of freedom does the treatment
sum of squares have? How about the error sum of
squares?
c) Assuming that the conditions are satisfied, what is the
P-value? What would you conclude?
d) What else about the data would you like to see in order
to check the assumptions and conditions?
