To obtain information on the corrosion-resistance properties of a certain type of steel co ured, yielding a sam State the appropriate null and alternative hypotheses. what would you conclude? (Use a = 0.05.) . H: H = 50 H : M > 50 O Hot M = 50 H : H # 50 O Ho: H # 50 He: H > 50 OH ! H > 50 H : M = 50 culate the test statistic and de cimal places.) Z = 3.78 -value = 0.0002 State the conclusion in the problem context. Do not reject the null hypothesis. The e that the true average penetration is more than 50 mils. . Reject the null hypothesis. There is su it the true average penetration is more than 50 mils. O Reject the null hypo erage penetration is more than 50 mills. O Do not reject the null hypothesis. There clude that the true average penetration is more than 50 mils. ou may need to use the appropriate table in the Appendix of Tables to answer this
