c. /7 Determine the characteristics of the comparison distribution (hint: it is a distribution of means):
mean of the comparison population's difference scores =
sample's difference scores (San Fran - Paris) =
degrees of freedom =
estimated variance of the comparison population's difference scores =
estimated standard deviation of the comparison population's difference scores =
variance of the distribution of means =
standard deviation of distribution of means =

e. /1 Determine your sample's score on the comparison distribution =
f. /1 Accept or reject the null hypothesis?
