Find the range and the standard deviation of the following prices of backpacks: $11.99, $8.84, $16.98, $9.99, $10.45, $10.86, $11.99. O A. Range = $8]14; standard deviation $2.08 O B. Range = $6.99; standard deviation $2.08 O C. Range = $8.14; standard deviation = $2.62 O D. Range $6.99; standard deviation $2.43
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.
