1. Use a P- value to test the claim about the population mean μ using the given sample statistics. State your decision for α = 0.05
Claim: μ ≠ 230; Sample statistics: x (bar) = 216.5, s = 17.3, n = 48

= _
2. If X =5.2, R =.3,and n=4, and if specifications are (4.6, 5.8), is the process capable? Show work.
= _
