which of the following best describes the distribution of data? negatively skewed postively skewed roughly symmetrical
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.

Since you have asked question related to the distribution of the data, we will solve that for you. If you want any specific question to be solved then please specify the question number or post only that question.
Here,on analyzing the histogram of the data,we can see that the longer tail of the distribution which represents the data is towards the higher values of the variable.This type of graphical characteristics is mainly analogous to a positively skewed distribution.
