In a test of corrosion resistance, a sample of 62 Incoloy steel specimens were immersed in acidified brine for 4 hours, after which each specimen had developed a number of corrosive pits. The maximum pit depth was measured for each specimen. The mean depth was 850 μm with a standard deviation of 153 μm. The specification is that the population mean depth μ is less than 900 μm.

Find the P-value for testing H0 : μ ≥ 900 versus H1 : μ < 900.

H(c)=6.4+0.6c 6.4 is the constant when the height of the cups is 18.4 the function is: 18.4=6.4+0.6c then you subtract 6.4 from both side to get: 18.4 - 6.4=6.4 + 0.6c - 6.4 12=0.6c c= 12/.6 c=20 H(c)= D. 6.4+0.6c) The number of cups in a 18.4 cm high stack is: D.20)
