QUESTION 13 Questions 13-14 The following are the duration times (minutes) of all missions flown by a space shuttle. Use the given data to construct a boxplot and identify the 5- number summary. 9 7477 8686 8871 9989 10,074 10,181 11,440 11,482 11,900 The 5-number summary is (Use one more decimal than the original data for Q1, the mean and Q 3).
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.
