Question 4

Fiefer to Table $6.1 - Facton for Computing Control Chant Limits (3 sigma) for Ris probiom. Eagietrons are al-electric automobles produced by Mogul Motors, Ine. Ore of the concems of Mogul Motors is that the Eagletens be capable of achieving appropriate maximum spoeds. To moniter this, Mogul executves take samples of ten Eagletrons at a fime For each sample, they determine the average maximum speed and the targe of the maximum speeds within the sample. They repeat this with 35 samples to obtain 35 sample means and 35 ranges. They find that the average sample mean is 93.50 miles per heur, and the average range is 4.50 miles per hour. Using approxemately a 0.0027 probabily that this is due to notural vaciation The control limits for the chart based on the above requirement for the given information are: UCLA= miles per hour (round the mponse to thee docimal places)
