In fact, for any number (or fraction) of standard deviations, we know exactly what percent of the data fall within that number of standard deviations of the mean. 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(.

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)

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.

Pop1 and Pop2 are normal density curves with means and standard deviations µ1, σ 1 and µ2, σ 2, respectively. Suppose that µ1 = µ2 and σ 1 = 2(σ 2). Consider these statements: I. Pop1 has twice as many observations within one standard deviation as Pop2. …

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.

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 ...
