The stem & leaf show demonstrates that 0.55 for both the data is indeed a reasonable value.
The probable outlier is the data value 0.76.
The variability of the techniques is relatively large.
It show isn't symmetrical and seems to be optimistic.
D. 50% will be long haired and 50% short haired
6.4 = 0.8m
/0.8 /0.8
8 = m
The numbers would be x and (2x-6).
We would have to solve the following equation.
x+(2x-6)=21
3x-6=21
3x=27
x=27/3=9 Then, the other number would be 2x-6=2*9-6=18-6=12
Answer: the numbers would be 9 and 12,
