      The empirical rule is a statistical rule that states that for a normal distribution, almost all data falls within three standard deviations (denoted by σ ) of the mean (denoted by µ ).Broken down, the empirical rule shows that 68% falls within the first standard deviation (µ ± σ) , 95% within the first two standard deviations (µ ± 2σ) , and 99.7% within the first three standard ...

      In many natural processes, random variation conforms to a particular probability distribution known as the normal distribution, which is the most commonly observed probability distributions. The normal curve was first used in the 1700’s by French mathematicians and early 1800’s by German mathematician and physicist Karl Gauss.

      From table or calculator the 90th percentile for standard normal distribution is at z=1.2816. So answer is 90 + 1.2816*38 mg/dL =138.7 mg/dL Suppose that the “abnormal range” is defined to be glucose levels which are 1.5 standard deviations above the mean or 1.5 standard deviations below the mean.

      Find the range of values that defines the middle 80% of the distribution of SAT scores (372 and 628). Find the z-scores - -1.28, 1.28. For a normal distribution, find the z-score that separates the distribution as follows: Separate the highest 30% from the rest of the distribution. .52. Separate the lowest 40% from the rest of the distribution. .25
