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.

Normal Distribution Calculations. Process: 1) Normality—table is for normal distributions (or at least approximately normal distributions only.) 2) state in terms of x and draw the curve. Label with µ,σ, x. 3) standardize with new graph (turn x into z). 4) use table A or calculator: normalcdf (lowerbound, upperbound, µ, σ)

Use the standard Normal distribution to calculate the proportion of values in a specified range and to determine a z-score from a percentile. Given that a variable has the Normal distribution with mean ( and standard deviation (, use Table A and your calculator to. determine the proportion of …

A normal distribution of scores has a standard deviation of 10. Find the z-scores corresponding to each of the following values: A score of 60, where the mean score of the sample data values is 40. Z=2. A score that is 30 points below the mean. z=-3.

For example, if a researcher knows that the statistics in the study follow a Z or standard normal distribution, there are two parameters that he/she needs to estimate, the population mean (μ) and the population variance (σ2). Most of the time, the researcher know one of the parameters and need to estimate the other.

Calculate the z-scores corresponding to both 12.1 and 12.76, and find the Standard Normal Probabilities for each, using a calculator or the Standard Normal Probabilities Table. Explain how you would use those values to determine the probability a bag chosen at random will contain between 12.1 and 12.76 oz.

For example, consider the normal curve percentages in the table below. Given a number z of standard deviations, the table gives the percent of data values between the mean ( and ((z(. Note that since this only includes data values above the mean, this is only half of the percent of data values within z standard deviations of the mean, i.e ...

b. T. Since the population has a normal distribution, the sampling distribution of is normal. So, we can use the z table. c. T. Since the population has a normal distribution, the sampling distribution of is also normal. So, we can use the z table. d. F. The distribution is not Normal because the 68,95,99.7% rule does not apply.
