Shannon is a graduate student studying health economics. One of her projects was to study the effects of tobacco product taxation on the frequency of smoking among college students. She hypothesized that the taxation would decrease the frequency of smoking. Using a survey analysis and a known frequency in a recently reported publication, she conducted a hypothesis test to determine if students were less likely to smoke if the tax rate went up by $0.25 per cigarette pack. She used a significance level of 2%.

Determine the critical value or values for a one-mean z-test at the 2% significance level if the hypothesis test is left-tailed (Ha:μ<μ0).

Suppose a graduate student is studying a population of bluebonnets along a roadside. The plants in this population are genetically variable. She counts the seeds produced by 100 plants and measures the mean and variance of seed number. The variance is 30. Selecting one plant, the student takes cuttings from it and cultivates them, producing many genetically identical clones. She then transplants these clones into the roadside population, allows them to grow for one year, and then counts the number...

Case Study: Shannon Shannon is a 30-year-old woman preparing to run her first marathon. She regularly runs 30km per week, attends the gym three times per week doing a mix of cardio- and weight training sessions and also plays touch football once a week in a social work team. She is up early most mornings and when she does not run will either practice yoga at home or do a 30- to 40-minute power walk. Shannon ran competitively throughout secondary...

A 34 year-old graduate student presents to the student health center with reddish, crusted lesions on his penis. He is treated with fungal cream. One week later he returns because the lesions are not getting better, and he is prescribed dicloxacillin (penicillin derivative) for a presumed staph infection. It’ been over 3 months since his initial visit, and the lesions on his penis have resolved. However, he now returns with a rash on his trunk and sees a different provider...

You are a graduate student studying an inducible transcription factor called X. You make a cellular lysate and carry out a series of centrifugation steps at increasing speeds to localize X. You find that prior to induction, X is the supernatant following a fourth, very high speed ultracentrifugation step; however, after induction it is located in the pellet after only one relatively low speed ultracentrifugation step. What might this tell you about how X is regulated? What other techniques might...

MG is a 27-year-old graduate student, recently married, who comes into the student health clinic for a routine pelvic test and Pap smear. During the course of the check-up, the gynecology resident performing the test obtains the Pap smear, but also obtains cervical cultures for gonorrhea and chlamydia. The examination concludes uneventfully. Several weeks later, MG receives a postcard indicating that the Pap smear was normal, with no evidence of dysplasia, but that the cervical culture for gonorrhea was positive....
