Let x = red blood cell (RBC) count in millions per cubic millimeter of whole blood. For healthy females, x has an approximately normal distribution with mean ? = 4.3 and standard deviation ? = 0.5.   (a) Convert the x interval, 4.5 < x, to a z interval. (Round your answer to two decimal places.)  < z (b) Convert the x interval, x < 4.2, to a z interval. (Round your answer to two decimal places.) z <  (c) Convert the x interval, 4.0 < x < 5.5, to a z interval. (Round your answers to two decimal places.)  < z <

Find the area of the shaded region. The graph to the right depicts IQ scores of​ adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15.                         102 126         A symmetric bell-shaped curve is plotted over a horizontal scale. Two vertical lines run from the scale to the curve at labeled coordinates 102 and 126, which are both to the right of the curve’s center and peak. The area under the curve between the vertical lines is shaded.       The area of the shaded region is enter your response here. ​(Round to four decimal places as​ needed.)
