1. In this problem you will do some hypothesis testing on a built-in R dataset. The dataset is PlantGrowth, and it contains samples of weights of harvests from fields that have undergone different treatments ("ctrl", "trt1", "trt2"). The question you will examine is whether each treatment improves plant yields compared to the control. You will assume that the variances of the different groups are the same (but unknown) and you want to set your critical value for type I error rate of 5%. (a) State the null and alternative hypotheses for evaluating treatment 1 and treatment 2 (separately) relative to controls. (b) Calculate the samples means and variances that are used in this hypothesis test. (c) Use R to generate the critical value for this experiment with a 95% confidence. Showy our code (paste). (d) Write the equations to generate the test statistics for both tests. Use R to calculate those test statistics and p-values. Show your code. (e) Explain, based on this analysis, if either treatment 1 and/or treatment 2 can be determined to improve yields.

Question 1 A steel pipe with grade A53 grade A Type E in the attachment 1 is portion of raw material need to be used in underwater welding for new ferry terminal in Langkawi. As a welding engineer your need to study the quality of the welding joint prior to commence the construction works. (a.) From the IIW carbon equivalent ($C_{eq}$) formula Calculate the carbon equivalence ($C_{eq}$) for A53, grade A pipe produced by electric resistance welding process. (b.) (c.) Name the main and secondary elements for $C_{eq}$ contributor in (a) by formula and from the actual figure. (d.) Discuss why we need to take consideration the $C_{eq}$ number in underwater welding?
