Suppose that scores on knowledge test are normally distributed with a mean of 60 and a standard deviation of 3.4 scores on an amplitude test are normally distributed with a mean of 110 and a standard deviation of 6.84 scored a 55 on the knowledge test and 106 on the aptitude test Kelly scored 67 on the knowledge test and 119 on the amplitude test. (a) which test did Boris perform better on using score to support your answer (b) which test did Callie perform better on using score to support your answer
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.
