The red blood cell count of a healthy person was measured on each of 15 days. The number recorded is measured in millions of cells per microliter ( $\mu \mathrm{L}$ ). $\begin{array}{lllll}5.4 & 5.2 & 5.0 & 5.2 & 5.5\end{array}$ $\begin{array}{lllll}5.3 & 5.4 & 5.2 & 5.1 & 5.3\end{array}$ $\begin{array}{lllll}5.3 & 4.9 & 5.4 & 5.2 & 5.2\end{array}$ a. Use a stem and leaf plot to describe the data. b. Describe the shape and location of the red blood cell counts. c. If the person's red blood cell count is measured today as 5.7 million cells per microliter, would this be unusual? What conclusions might you draw?

Step 1
A stem and leaf plot is a graphical representation of the data. The "stem" is the leftmost digit(s) and the "leaf" is the rightmost digit. For this data, the stem and leaf plot would look like this: 4 | 9 5 | 0 1 2 2 2 2 2 3 3 3 4 4 4 5 Show more…

The red blood cell counts (in millions of cells per microliter) for a population of adult males can be approximated by a normal distribution, with a mean of 5.3 million cells per microliter and a standard deviation of 0.5 million cells per microliter. (a) What is the minimum red blood cell count that can be in the top 25% of counts? (b) What is the maximum red blood cell count that can be in the bottom 15% of counts? (a) The minimum red blood cell count is _______ million cells per microliter. (Round to two decimal places as needed.)
