Thank you very much for answering me. Can you please answer the d sub parts. The corrosion loss (in mm) was measured for eight specimens of a certain steel alloy that had been immersed in brine. The measurements were 0.3457,0.3755 , 0.3563, 0.3663, 0.3861,0.4007, 0.3429, 3769 . a. Make a dotplot of the eight values. b. Should the Student’s ? distribution be used to find a 99% confidence interval for the mean corrosion loss? If so, find the confidence interval. If not, explain why not. c. Eight independent measurements are taken of the corrosion loss for a different alloy. The measurements this time are: 0.3633, 0.4215 , 0.3429, 0.3501, 0.4974, 0.3678, 0.3896, and 0.3791. Make a dotplot of these values. d. Should the Student’s ? distribution be used to find a 95% confidence interval for the mean corrosion loss for this alloy? If so, find the confidence interval. If not, explain why not
