Consider the distribution of the prices of 15-pound bags of 17 different brands of dog food. Complete parts (a) through (d) below. a. How many peaks would you expect for the distribution? O A. There would probably be three peaks, one for the low priced items, one for the average priced items, and one for the high priced items. O B. There would probably be no peaks. The prices of competing products tend to form a uniform distribution. OC. There would probably be many peaks corresponding to the different brands. O D. There would probably be one peak because there are no obvious reasons why the prices of dog food would form different groups. b. Make a sketch of the distribution. Choose the correct answer below. O A. O B. Oc. OD. Q
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.
