Ise the following cell phone airport data speeds (Mbps) from a particular network. Find the percentile corresponding to the data speed 1.2 Mbps. 0.3 0.3 0.3 0.3 0.4 0.4 0.4 0.5 0.5 0.7 D 0.8 0.8 0.8 0.9 0.9 1.2 1.3 1.3 1.5 1.9 1.9 2.2 2.2 2.4 2.6 2.6 2.7 3.7 3.7 3.8 4.3 4.6 5.4 6.2 7.5 7.5 7.6 7.7 10.2 10.7 11.3 11.8 12.7 12.7 13.4 13.4 13.9 14.3 14.4 28.4 Percentile of 1.2% D (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.
