Medical: Red Blood Cell Count 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, the mean of the x distribution is about 4.8 a 0.01. s 1.9 ppb. x 7.2 m 8.0 a 0.05. x 17.9 s 5.2 m 19.4. m 19 inches? a x 18.5 s 3.2 inches. m 19 inches. a 0.01. m 1.75. s 0.82 x 2.05 x 8.1 s 1.9. m 7.4 s 18.5. x 36.2 Section 9.2 Testing the Mean m 427 . . .
