We know that:
Mean = 82 mm and SD = 10 mm ( standard deviation )
82 - 3 * SD = 82 - 3 * 10 = 82 - 30 = 52 mm
82 + 3 * SD = 82 + 3 * 10 = 82 + 30 = 112 mm
Population between 52 and 112 mm is within +/- 3 standard deviations from the mean.
By the 66- 95 - 99.7 % rule it is: 99.7% of the test group.
0.977 * 500 = 498.5
Answer:
99.7 % of the test group have a diastolic pressure between 52 and 112 mm, or 498 men.
Answer:
can you send a picture please so i can see it?
Answer:
you would get your answer by timesing all the numbers together, that it gives you.
Step-by-step explanation:
If my math is correct it would be the second one.
The algebraic expression would be that Quarters = 25 - W
It would be around 9.304. so you'd round to the nearest tenth 9.3
