a. Calculate the Sum of Squares (SS) for the above data. What
is the value of the correction term (CT)?
b. According to the physiotherapist the above group of
women should at least walk 5.0 km/day. Is the mean
distance walked by these women significantly different
from the required distance?
c. The sample size for the above problem is increased to 300
(n=300). The mean distance walked by this larger group is
4.5 km/day with a standard deviation of 0.8 km. Is this
distance significantly different from the required distance
of 5 km/day?
