Question

Eagletrons are​ all-electric automobiles produced by Mogul​ Motors, Inc. One of the concerns of Mogul Motors is that the Eagletrons be capable of achieving appropriate maximum speeds. To monitor​ this, Mogul executives take samples of eight Eagletrons at a time. For each​ sample, they determine the average maximum speed and the range 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 103.50 miles per​ hour, and the average range is 3.50 miles per hour. Using these​ results, the executives decide to establish an​ R-chart. They would like this chart to be established so that when it shows that the range of a sample is not within the control​ limits, there is only approximately a 0.0027 probability that this is due to natural variation.What will the upper control limit (UCL) and the lowercontrol limit (LCL) in this chart?

Answer 1

Answer: UCL= 5.592 LCL= .408

Answer 2

See explaination and attachment

Explanation:

Average can be defined as a number expressing the central or typical value in a set of data, in particular the mode, median, or (most commonly) the mean, which is calculated by dividing the sum of the values in the set by their number.

Range can be defined as the difference between the largest and smallest values.
