Use the following cell phone airport data speeds (Mbps) from a particular network. Find the percentile corresponding to the data speed 3.8 Mbps. 0.1 0.1 0.2 0.2 0.2 0.5 0.5 0.5 0.6 0.6 O 0.8 0.8 0.9 0.9 0.9 1.3 1.4 1.4 1.5 1.5 1.6 2.2 2.3 2.6 2.8 2.9 3.1 3.5 3.6 3.8 4.4 4.6 4.6 4.9 5.2 6.2 8.2 8.4 9.8 10.7 11.1 11.3 11.4 11.7 11.7 12.1 12.5 14.2 15.1 28.3 Percentile of 3.8 =| (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.
