A random sample of 25 students in a school shows that the mean number of hours of sleep per night is 7.4 and the MAD (mean absolute deviation) is 0.4.
Select the statement that is true.
A. The mean of this sample is likely to be the same as the mean number of hours of sleep per night of all students

Step-by-step explanation:
9
Step-by-step explanation:
- Plug the values into the distance formula.
√(x2 - x1)² + (y2 - y1)²
√[2 - (-7)]² + [-8 - (-8)]²
√(9)² + (0)²
√81
= 9
