Discrete Distributions Section6em ah baiTicket Machine SetupSuppose you have a machine that randomly prints out tickets with numbers on them. 17% of the timethe ticket has number 3. 24% of the time the ticket has number 8. 37% of the time the ticket hasnumber 15. 22% of the time the ticket has number 22. There are no other ticket numbers. Let therandom variable X be the number on the ticket.14. Use the Ticket Machine Setup. Find the variance for the distribution of X.A. 38.2676С. 42.2676D. 44.2676В. 40.2676

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).

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.
