Here are some summary statistics for the percentage of salt content for two seasoning blends a company produces. Blend Mean salt content Standard deviation Seasoning salt H= 56% o = 3% %3D Cajun seasoning p= 46% o = 2% Kaylee bought a bottle of seasoning salt that contained 59% salt and a bottle of Cajun seasoning that contained 44% salt. Relative to the type of blend, which bottle had a lower salt content? Kaylee's bottle of seasoning salt Kaylee's bottle of Cajun seasoning Both of her bottles had egual salt content relative to their blends. It's impossible to say without seeing all of the individual salt contents. It's impossible to say since we don't know the shape of either distribution.
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
