[Use Exam1-Data.xlsx] Find the Z-score of the “PER” value of the observations for all years and companies, and find the skewness of the distribution of the values ​​excluding any outliers with Z-score higher than 3 or lower than -3 using filter. (For example, if 1 out of 10 observations is an outlier, you can discuss the distribution of the 9 observations after filtering out the 1. DO NOT REMOVE THE OBSERVATIONS)You can check the distribution with a clustered column chart. A left-skewed distribution means a distribution with a tail that is longer on the left than on the right. A right-skewed distribution means a distribution with a tail that is longer on the right than on the left. Normal distribution means a distribution that is not skewed in any way. Exam1_Data.xlsx
