      De Moivre developed the normal distribution as an approximation to the binomial distribution, and it was subsequently used by Laplace in 1783 to study measurement errors and by Gauss in 1809 in the analysis of astronomical data (Havil 2003, p. 157). The normal distribution is an extremely important probability distribution in many fields.

      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

      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.

      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 ...

      Since the total area under the curve of a normal distribution is 1, this probability can be calculated by finding the area under the normal curve for that interval. To find areas under any normal distribution, you can either use your calculator or tables. We will use Z to denote the standard normal distribution and will consider 3 cases:
