Q9. Consider the baseball coefficient of restitution data as follows: 0.6248, 0.6520, 0.6226, 0.623O, 0.6237, 0.6368, 0.6280, 0.6131, 0.6118, 0.6220, 0.6096, 0.6223, 0.6159, 0.6151, 0.6300, 0.6297, 0.6298, 0.6121, 0.6107, 0.6435, 0.6192, 0.6548, 0.6392, 0.5978, 0.6351, O.6128, 0.6134, 0.6275, 0.6403, 0.6310, 0.6261, 0.6521, 0.6065, 0.6262, 0.6049, 0.6214, 0.6262, 0.6170, 0.6141, 0.6314. Suppose that any baseball that has a coefficient of restitution that equal or exceeds 0.63 is considered too lively. Find a 95% Cl of proportion of too lively. 0.116 sus 0.384 0.039
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.
