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.
I need help with ONLY these questions but I am adding the rest of the assignment so you can get some idea of what context the questions are pertaining to. Here are the 3 questions I need help with in bold. The bottom is the part the 3 questions are referring to. Thanks
3) For the previous problems, what are the units (as in miles, feet, gallons, etc.) for…
a. …the
b. …the standard deviation?
c. … the z-scores? (Hint: Consider the units you know in the z-score formula.
Heres the rest that should help answering the above:
Men Women
mean = 69.0, standard deviation = 2.8 mean = 63.6, standard deviation = 2.5 Heres the questions the above is referring to:
