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.
![An electronics company wants to compare the quality of their cell phones to the cell phones from three competitors. They sample 10 phones from each company and
count the number of defects for each phone. If ANOVA was used to compare the average number of defects, then the treatments would be defined as
Select one:
a the four companies
b.None is correct
c.the average number of defects
d.the total number of phones
O e.the number of cell phones sampled](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fde1da679-b360-4712-b298-5c18be8f5c44%2F94dd9fd0-eec5-4757-8ffb-bf0cc5db6eaa%2Frmi2s3_processed.png&w=3840&q=75)
