Question
The "Freshman 15" refers to the belief that college students gain 15 lb (or 6.8 kg) during their
freshman year. Listed in the accompanying table are weights (kg) of randomly selected male
college freshmen. The weights were measured in September and later in April. Use the listed
paired sample data, and assume that the samples are simple random samples and that the
differences have a distribution that is approximately normal. Complete parts (a) through (c).
September
58 68 64 71 80 64 56 57 52
April
56 69 68 69 82 68 55 59 57
a. Use a 0.01 significance level to test the claim that for the population of freshman male college students, the weights in September are less than the weights in the following April.
In this example, Hd is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the April weight minus the September weight. What
are the null and alternative hypotheses for the hypothesis test?
