Answer:
For the student who is studying 10 hours a week is in the 57.93th percentile.
Step-by-step explanation:
Corresponding z-score for the student who studies 10 hours a week can be calculated by the formula
z=
where
- x is the hours student work in a week, which is 10,
- M is the mean studying hour of the class, which is 9.92,
- s is the standart deviation which is 4.54
from here we find that z=
≈0.2
Corresponding percentile for z=0.2 is 57.93
Here are the coordinates:
(60, 105)
(62, 114)
(64, 124)
(66, 131)
(68, 139)
(70, 149)
(72, 158)
Step-by-step explanation: All you have to do is take the values for y and x and plug them in to get the coordinates that you need. After doing that, use the line that you've created and find a point that would fall directly above 75, or use the line of best fit (in a scatterplot, this is a line that fits most of the points).
