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.

Because of a wage increase, February profits are lower than January profits. The profit per car is
tabulated by model as shown in Table 2.

Table 2: Profit per car
i) Assuming that all cars produced were sold, giving your answer in tabular form; calculate the daily
profits from each plant for both January and February? [Hint: Represent the given informations
in matrices and perform matrix multiplication]
ii) What was the daily profit in January from the Windhoek plant?
iii) What was the total daily profit (from all three plants) in February?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fcaf7c4d6-9adc-4114-a67f-4cfeb716e2c8%2Fe32850d9-1474-479e-bbac-10e8e9daf8db%2Fa209jkq_processed.jpeg&w=3840&q=75)
