Use the following cell phone airport data speeds (Mbps) from a particular network. Find the percentile corresponding to the data speed 11.2 Mbps. 0.2 0.2 0.2 0.2 0.2 0.3 0.3 0.3 0.4 0.4 0 0.5 0.6 0.7 0.8 0.9 0.9 1.2 1.3 1.3 1.6 1.6 2.2 2.2 2.5 2.8 2.9 3.1 3.5 4.4 48 4.8 5.2 5.8 8.8 8.9 9.5 9.6 10.1 11.1 11.2 11.3 12.4 12.8 13.1 13.3 13.5 13.6 13.8 14.1 25.6 Percentile of 11.2 =| (Round to the nearest whole number as needed.)
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.
