Quizplus · Accepted Answer

To find the mean of Group 1, we need to add up all the values in that group and divide by the number of values. 
Adding up:
127.27 + 118.46 + 118.92 + 112.68 + 122.44 = 599.77
Dividing by 5:
599.77/5 = 119.954
Rounding to two decimal places: 119.70 
Therefore, the mean of Group 1 is 119.70.
