According to a study conducted by NASA, the average breadth of an adult man's hand is 3.5 inches.* The standard deviation is 0.05 inches. Sweden wants to send its scientist Dr. Narks Larssen into space and is designed his astronaut suit. Dr. Larssen has a hand breadth of 3.32 inches. What is the z-score for his hand breadth? * An actual statistic! Group of answer choices -0.28 -3.60 3.60 0.28
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.
