Answer:
0.86 (Approx)
Step-by-step explanation:
Given:
n = 35
P = 55% = 0.55
Q = 1 - p = 0.45
Computation:
Standard deviation σ = √npq
Standard deviation σ = √(35)(.55)(.45)
Standard deviation σ = 2.9432
Mean μ = np = 35 x 0.55 = 19.25
p[(x-np)/ σ ]
P[z<1.04204]
= 0.86 (Approx)
X - 8 = 12, add 8 to 12. The answer is 20.
Answer:
8.75
Step-by-step explanation:
