Problem 3: Let x be a random variable that represents red blood cell count (RBC) in millions of cells per cubic millimeter of whole blood. Then x has a distribution that is approximately normal. For the population of healthy female adults, suppose the mean of the x distribution is about 4.68. Suppose that a female patient has taken six laboratory blood tests over the past several months and that the RBC count data sent to the patient's doctor are as follows. At the 5% significant level, we wish to know if the data provide sufficient evidence to conclude that the population mean RBC count for this patient is not 1.68. 4.9 | 4.2 | 4.5 | 4.1| 4.4 | 4.3
