What is the probability that a tractor came from the red company given that it was defective? P(ROD) P(R|D)= P(D)
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.
All tractors made by a certain company are produced on one of three assembly lines, named Red, White, and Blue. The chances that the tractor will not start when it rolls off of a line are 6%, 11%, and 8% fors lines Red, White, and Blue, respectively. The percentages of all tractors produced on each line are: Red: 48% White: 31% Blue: 21% What is the probability that a tractor came off the White line, given that it wouldn't start? with tree diagrams
