Find the mean of the data summarized in the given frequency distribution. Compare the computed mean to the actual mean of 50.2 miles per hour. Speed (miles per hour) Frequency 42 - 45 46 - 49 50-53 54 -57 58 - 61 28 13 1 The mean of the frequency distribution is (Round to the nearest tenth as needed.) miles per hour. Which of the following best discribes the relationship between the computed mean and the actual mean? O A. The computed mean is close to the actual mean because the difference between the means is less than 5%. O B. The computed mean is not close to the actual mean because the difference between the means is more than 5%. O C. The computed mean is not close to the actual mean because the difference between the means is less than 5% O D. The computed mean is close to the actual mean because the difference between the means is more than 5%.

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.
