Let x be a random variable that represents red blood cell counts (RBC) with a normal distribution. For the population of healthy female adults, the mean is about 4.6. Suppose that a female patient has taken six laboratory blood tests and the RBC count data are as follows: {4.9, 4.2, 4.5, 4.1, 4.4, 4.3}. Given the sample, x = 4.40 and s = 0.28. Does the given data indicate that the RBC mean for this patient is lower than 4.6? Use alpha =.01.
