Probiems: 1. Ford Taurus Assembly Time: Let x be a random variable that represents assembly times for the Ford Taurus. The Wall Street journal reported that the average assembly time is ,u = 38 hours. A modification to the assembly procedure has been made. Experience with this new method indicates that the population standard deviation of the assembly time is 1.2 hours. It is thought that the average assembly time may be reduced by this modification. A random sample of 47 new Ford Taurus automobiles coming off the assembly line showed the average assembly time of the new method to be it: 37.5 hours. Does this indicate that the average assembly time has been reduced? Use a: = 0.01 . A) To be investigatedICLAlM: Do the data indicate that the average assembly time has been reduced? The key word "reduced\" translates to "less than" so the claim is H1. State hypotheses in symbols and State hypotheses in words in the context of the pmbiem. determine which one is the doim. Ho: u = 38 hours The average assembly time for the Ford Taurus is 38 hours. (Note: This is saying the new method does not reduce the average assembly time.) H1: 11
