Use a digit before the last one of your student ID ( I called it b) to do the following problem.Test the given hypothesis. Assume that the population is normally distributed and that the sample hasbeen randomly selected. A manufacturer uses a new production method to produce steel rods. A randomsample of 37 steel rods resulted in lengths with a mean b+1 and standard deviation of 4.7 cm. At the 0.10significance level, test the claim that the new production method has mean 5.5 cm, which was the meanfor the old method. a=6
