Question 15
MTNAT1 markNeeds review
The grain size (X) of annealed specimens follows a symmetric distribution with a mean (μ) of 5 μm and a standard deviation (σ) of 0.5 μm. The percentage of specimens with grain size in the range 5 to 6 μm is expected to be: __________ (round off to nearest integer).
Given: For the symmetric distribution: Probability P(X ≤ μ + 2σ) = 0.98
