Consider the estimated equation (standard errors in parentheses): ?ˆ=15.83+0.829?y^=15.83+0.829x If all values of ?x were
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.
Q 4. Consider the estimated equation (standard errors in parentheses):
?ˆ=15.83+0.829?y^=15.83+0.829x
If all values of ?x were divided by 20 before estimating, the estimated equation would be:
?ˆ=15.83+0.041?y^=15.83+0.041x
?ˆ=0.792+0.041?y^=0.792+0.041x
?ˆ=316.6+16.58?y^=316.6+16.58x
?ˆ=15.83+16.58?
