a. Construct a stem-and-leaf display. Round the data to the nearest ten dollars and complete the stem-and-leaf display on the right. Split each stem into two parts, the first part being 00-40 for the leaves and the second part being 50-90. For example, the value of 570 would correspond to 5|7. (Use ascending order.)
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.
The table below contains the total cost (in $) for four average-priced tickets, two beers, four soft drinks, four hot dogs, two game programs, two adult-sized caps, and one parking space for 30 basketball arenas. Complete parts (a) and (b) below.
