The mean for statistics test scores is 61 and the standard deviation is 6.0. For the biology test scores, the mean is 22 and the standard devaton is 37. The et scores of a student who took bob s re gen to Asludent gets a 74 on the statistics test and a 24 on the biology test (a) Traneform each test score to aecore (b) Determine on which test the student hada better score (a) Transform the statistice lest score to a 2-core. (Type an integer or decimal rounded to the nearest hundredh as needed)
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.
