Transcribed Image Text:### Example Problem 7.2.3
**Context**: A synthetic fiber used in manufacturing carpet has tensile strength that is normally distributed.
**Given**:
- Mean tensile strength (\(\mu\)) = 75.5 psi
- Standard deviation (\(\sigma\)) = 3.5 psi
- Sample size (\(n\)) = 6
**Objective**: Find the probability that a random sample of 6 fiber specimens will have a sample mean tensile strength that exceeds 75.75 psi.
To solve this problem, consider using the properties of the sampling distribution of the sample mean and apply the Z-score formula.
