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.

Compute the test value. Is there a sufficient evidence at the 0 05 level of significance to
conclude that there is a difference in mean fiber content among breakfast cereals, fruits,
and vegetables?
O A) test value: 4.932
Conclusion: Yes, there is a significant difference in mean fiber content among
breakfast cereals, fruits and vegetables at the 5% level of significance.
O B) test value: 4.932
Conclusion. Yes, there is no significant difference in mean fiber content among
breakfast coreals, fruits and vegetables at the 5% level of significance.
O C) test value: 1.991
Conclusion: There is a significant difference in mean fiber content among breakfast
cereals, fruits and vegetables at the 5% level of significance.
O D) test value: 1.991
Conclusion: There is no significant difference in mean fiber content among
breakfast cereals, fruits and vegetables at the 5% level of significance.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9483684e-c1ef-4d54-9bd0-1fc6f5e6bedc%2Fb5ef719b-cc1b-4632-b5c7-160e31b0e890%2Fgn9fzrq_processed.jpeg&w=3840&q=75)
