Medical: Red Blood Cell Volume Total blood volume (in ml) per body weight (in kg) is important in medical research. For healthy adults, the red blood cell volume mean is about (Reference: Laboratory and Diagnostic Tests, F. Fischbach). Red blood cell volume that is too low or too high can indicate a medical problem (see reference). Suppose that Roger has had seven blood tests, and the red blood cell volumes were 32 25 41 35 30 37 29 The sample mean is Let x be a random variable that represents Rogers red blood cell volume. Assume that x has a normal distribution and Do the data indicate that Rogers red blood cell volume is different (either way) from Use a 0.01 level of significance.
LAB ACTIVITY 1 Welcome to the first “real” lab assignment of the semester! Remember that each lab assignment (including this one) will be worth 10 points. You’ll get to keep your best 12 lab assignment grades, so there are 120 points possible (out of 500 total) on all of your labs. The primary goal of today’s lab is to introduce you to Minitab, the statistical software we will use for this class. Complete this worksheet—with a partner if you wish—and at the end you will be asked to submit your answers in ANGEL. Each student must turn in the lab individually, even if you teamed up during the lab class. If you get stuck on anything, help is available! Check with the folks around you, and if you all have the same question then flag down the teaching assistant or the lea
