Answer: Choose the graph which corresponds to the area above 13.4 for a N(10,2) distribution.
Solution:
Z score = x - μ / σ
Z score = 13.4 - 10 / 2
Z score = 1.7
P-value:
P(x >13.4) = 1 - P(x<13.4)
P(x >13.4) = 1 - 0.9554 (from z table)
P(x >13.4) = 0.0446
Therefore,
The second graph is correct answer.
