Q#5- The table tvalue associated with the upper 5% of the tdistribution and 12 degrees of freedom is . FILL IN HE BLANK WITH THE CORRECT ANSWER. SHOWTHE STEPS. ANS: Q# 6- Consider the following null and alternative hypotheses. HO: = 67 Ha: E] 67 Do these hypotheses indicate one or two tailed test? Explain. ANS: Q#7 a) What is probability value approach? ANS: b) Collinsville Construction Company purchases steel rods for its projects. Based on previous tests, Claude Carter, Quality Assurance Manager, has recommended purchasing rods from Redding Rods, lnc. (population 1), rather than Stockton Steel (population 2), 1 since Redding's rods had less variability in length. Recently, Stockton revised it rod shearing operation, and Claude has sampled the outputs from Redding's and Stockton's rod manufacturing processes. The results for Bedding were 312 = 0.10 with n1 = 8, and, for Stockton, the results were 522 = 0.05 with n2 = 10. Assume that rod lengths are normally distributed in the population. If II: 0.05, the observed Fvalue is . FILL IN THE BLANK WITH THE CORRECT ANSWER. SHOW THE STEPS TO ARRIVE AT THE
