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.
![A study shows that running increases the percent resting metabolic rate (RMR) in older women. The average RMR of 35 elderly women runners was 32.7% higher than the average RMR of 35
sedentary elderly women, and the standard deviations were reported to be 10.5% and 10.2%, respectively. Was there a significance increase in RMR of the women runners over the sedentary
women? Assume the populations to be approximately normally distributed with equal variances. Use a P-value in the conclusion.
