Standard deviation is used to determine how the values in a group differs from the mean of the values in the group.
In order to determine the standard deviation, take the following steps:
• Determine the mean of the observation: 14
Determine the difference between each value and the mean and then square the result: (12 - 14)² + (14 - 14)² + (9 - 14)² + (21 - 14)² = 78
Determine the mean of the sum of the squared differences and then find the square root of the mean: √78/(n - 1) = 5.1

Step-by-step explanation:
Maria can do full job in 13 hours,
she can do 1/13 part of job in one hour
Felipe can do full job in 15 hours,
he can do 1/15 part of job in 1 hour
Together they can do:
- 1/13 + 1/15= 28/13*15= 28/195 of job in 1 hour
to complete full job they need:
- 1 ÷ 28/195= 195/28 ≈ 7 hours
