In a test of corrosion resistance, a sample of 62 Incoloy steel specimens were immersed in acidified brine for 4 hours, after wh

ich 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.

Answer:

0 > -5

Step-by-step explanation:

9w - 4w + 6 > 1 + 5w

add the similar variables

5w + 6  > 1 + 5w

subtract  6 from both sides

5w + 6  > 1 + 5w

       -6     -6

5w > 5w - 5

simplify

5w > 5w -5

subtract 5 w from both sides

5w > 5w -5

-5w    -5w

simplify

= 0 > -5
