• Sample size
• Mean
• Median
• Mode
• Standard deviation

This is an answer from another student. I need a reply to their answer with a minimum of 100 words and without any references.

“The null hypothesis would be that there is no difference in contribution between managers or individual employees. The alternative hypothesis would be that there is a difference in contribution between managers and individual employees. The data for this analysis was obtained by a coworker, not sure the method that was used.

The sample size is 53 individuals which consists of 25 managers and 28 individual contributors.

The mean for managers is 59.24.

The mean for individual contributors is 42.39

The overall mean is 50.33

The median for managers is 67.

The mode for managers is 78, 54, 56, 67, 23.

The median for individual contributors is 35.

The mode for individual contributors is 23.

The overall median is 45.

The overall mode is 23.

The standard deviation for this data group is 28.7

According to the results, the null hypothesis is wrong since there is a difference in contribution between managers and individual employees.”
