To determine which statement is true, we should analyze the standard deviations (SD) given for each nap, as the standard deviation measures the consistency or variability of the durations.
1st Nap: Mean = 83, SD = 9
2nd Nap: Mean = 52, SD = 6
3rd Nap: Mean = 39, SD = 11
Now let's evaluate each statement:
A. The 1st nap is the least consistent in duration because its mean is the highest.
- This statement incorrectly suggests that the
