The box plots show the target heart rates of men 20-40 years old and men 50-70 years old. Target Heart Rates of Men 20-40 years old 50-70 years old 70 80 90 100 110 120 130 140 150 160 170 Beats per Minute Which statement is best supported by the information in the box plots? A The range of the data for men 20-40 years old is less than the range of the data for men 50-70 years old. B The median of the data for men 20-40 years old is less than the median of the data for men 50-70 years old. C The minimum target heart rate for men 20-40 years old is less than the minimum target heart rate for men 50-70 years old. D The interquartile range of the data for men 20-40 years old is greater than the interquartile range of the data for men 50-70 years old.
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.
