Z-scores can be used to assess whether data values in a certain distribution are unusual. This is appropriate when the data distribution is approximately bell-shaped. The National Oceanic and Atmospheric Administration (NOAA) reports that, from 1971 to 2000, July average temperatures in West Central Indiana had a mean of 74.5°F with a standard deviation of 2.0°F.‡ Make sure that you fill in each answer area before checking "How Did I Do?". Is it reasonable to assume that July average temperatures...

Using the accompanying table of data, blood platelet counts of women have a bell-shaped distribution with a mean of 255.1 and a standard deviation of 65.3. (All units are 1000 cells/muL.) Using Chebyshev's theorem, what is known about the percentage of women with platelet counts that are within 2 standard deviations of the mean? What are the minimum and maximum possible platelet counts that are within 2 standard deviations of the mean?
