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.
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 distribution above shows strong signs of a normal distribution. The distribution above shows signs of a normal distribution but there is a trend for late night shopping. Resource: the-shape-of-business-worksheet.DOCX. Understanding the standard deviation. Students should investigate the idea of spread and how it is represented mathematically.
For the standard normal distribution: µ = 0 and σ = 1. The output on your calculator will be a Z-SCORE, so round it to 2 decimals! Examples: a) Find the z-score so that the area under the standard normal curve to its . LEFT. is 0.0262. b) Find the z-score so that the area under the standard normal curve to its . LEFT. is 0.9931.

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
Normal Distribution Calculator with step by step explanation
Normal distribution calculator Enter mean, standard deviation and cutoff points and this calculator will find the area under normal distribution curve. The calculator will generate a step by step explanation along with the graphic representation of the area you want to find.
Sketch a normal distribution curve, enter the given probability or percentage in the appropriate region of the graph, and identify the x value(s) that you’re looking for. Refer to the body of table A-2 to find the closest area to the left of x & then identify the corresponding z score
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:
