Answer:

Step-by-step explanation:
Answer:
A.) 67.78
B.) 76.48
C.) 87.34
Step-by-step explanation:
Given that:
Mean (m) = 80.6
Standard deviation (σ) = 10
A.) 10th percentile :
10th percentile corresponds to a Zscore of - 1.282
Zscore = (x - m) / σ
-1.282 = (x - 80.6) / 10
-12.82 = x - 80.6
x = -12.82 + 80.6
x = 67.78
B.)34th percentile of blood pressure ;
34th percentile corresponds to a Zscore of - 0.412
Zscore = (x - m) / σ
-0.412 = (x - 80.6) / 10
-4.12 = x - 80.6
x = - 4.12 + 80.6
x = 76.48
C.) third quartile = 75% = 0.75
75th percentile corresponds to a Zscore of 0.674
Zscore = (x - m) / σ
0.674 = (x - 80.6) / 10
6.74 = x - 80.6
x = 6.74 + 80.6
x = 87.34
-10x^2+10x+32 is the simplified answer
