A hypothesis test will be done to verify if the claim is true and also a conclusion will be made. To see if what the customers are saying is true about the ounces in the bottles are actually less than what is advertised the first thing that needs to be done is the calculations of the mean‚ median‚ and standard deviation for the

turnover rate? Step 2- Comparing the means of two or more groups HR has gathered data from two groups of engineers‚ Design Engineers and Manufacturing Engineers. The same survey was used from both groups and the same numbers of employees were surveyed. The numbers from the survey were added and then divided by the number of data points to identify the mean of both data sets. Now the average range for both groups is known and can be compared. After comparing the mean of the two groups you can then compare
