The following data are the Medical Expenses in each of the 50 states. Using descriptive statistics, measures of central tendency, and measures of dispersion, answer the following questions below. The data is in thousands of dollars and is arranged in alphabetical order Q 1: Using the formula: (2 ^^ k> n.) Determine the result of that mathematical operation, to determine the number of classes. Q 2: Based on the previous result. Determine the number of classes. Q 3: Using the formula: cl
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.

Q 1: Using the formula: (2 ^^ k> n.)
Determine the result of that mathematical operation, to determine the number of classes.
Q 2: Based on the previous result. Determine the number of classes.
Q 3: Using the formula: class width = H - L / (number of classes). Determine the result of that mathematical operation to two decimal places to determine the width of the classes.
Write the result as follows (XXX .XX)
Q 4: Based on the previous result, determine the width of each "Cute Width" class if the initial value of the first class is 400 and the final value of the last class is 1300.
Q 5: Based on the previous result Determine the final value of the first class.
Q 6: Determine the Midpoint of the first class
Q 7: Determine the final value of the third class
