Answer:
0.00000046997
Explanation:
→ Set up normal distribution without sample size
x ∼ N ( 12 , 84² )[tex]x[/tex]
→ Set up normal distribution with sample size
[tex]x\alpha N(12,\frac{84^{2} }{36})[/tex]
→ State probability to find
p ( 80.54 < x < 88.9 )
→ Use calculator to find the values
Lower = 80.54, Upper = 88.9, σ = √84² ÷ 36 and μ = 12
