please help me with this problem.

The "Freshman 15" refers to the belief that college students gain 15 lb (or 6.8 kg) September 63 64 57 65 56 64 75 87 64 during their freshman year. Listed in the accompanying table are weights (kg) of April 64 68 58 68 53 66 82 88 68 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). a. Use a 0.05 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, He 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? Ho: Hd kg H1: Hd kg (Type integers or decimals. Do not round.) Identify the test statistic. t=(Round to two decimal places as needed.) Identify the P-value. Quest
