The Current Results website lists the average annual high and low temperatures (degreesfahrenheit) and average annual snowfall (inches) for fifty-one major U.S. cities, based ondata from 1981 to 2010. The data are contained in the file Snow. for example, the average low temperature for Columbus, Ohio is 44 degrees and the average annual snowfallis 27.5 inches.a. Construct a scatter diagram with the average annual low temperature on the horizontalaxis and the average annual snowfall on the vertical axis
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.
