Transcribed Image Text:The distribution of batting averages for all Major League Baseball players very closely follows a normal
distribution, with a population mean of 0.261 and a standard deviation of 0.033,
The 68-95-99.7 Rule for Normal Distributions
According to the 68-95-99,7 rule, in any normal distribution:
RULE
Quartiles of a Normal Distribution
About 68% of the observations fall within
About 95% of the observations fall within 2 standard deviations of the mean.
About 99.7% of the observations fall within 3 standard deviations of the
DEFINITION
The quartiles of a normal distribution are located about 0.67 (which is about
2/3) of a standard deviation away from the mean. In particular, the first quartile is
located at 0.67 standard deviation below the mean, and, by symmetry, the third
quartile is located at 0.67 standard deviation above the mean.
