Answer:
Maximum beat per minute for the lower 40% can be 77.
Step-by-step explanation:
Let z* be the z-score associated to the lower 40% bound. Then
P(z<z*)=0.4 By looking one tail z-table, we can find that z*=−0.253.
Let X be the maximum pulse rate among the pulse rates in the lower 40%. Then
z*=-0.253= where
- X is the maximum pulse rate of the lower 40%
- M is the mean resting pulse rates of all students at Adams High School (80 beats per minute)
- s is the standard deviation of resting pulse rates of all students at Adams High School (9 beats per minute)
-0.253= and we get X=(-0.253×9)+80=77.723
Since beats per minute can be positivive integer, maximum beat per minute for the lower 40% can be 77
