Answer:
80.67 hours
Step-by-step explanation:
Data provided in the question:
The number of weekly hours worked :
78 85 82 79 77 82 81 82 81 81 82 78
total number of observations = 12
Now,
Mean = (Sum of all the data values) ÷ (Total number of data values)
or
Mean = ( 78 + 85 + 82 + 79 + 77 + 82 + 81 + 82 + 81 + 81 + 82 + 78 ) ÷ 12
or
Mean = 968 ÷ 12
or Mean = 80.67 hours
