Birdseye Magnetronics makes induction meters used in vending machines to test the validity of coins. Their specifications require the induction reading capability of the meters to fall between 0.25 and 0.50 Tesla (T) units. Quality analysts took 3 random test readings of 30 meters, available in the Problem 1 Data.

1.) Compute the mean and standard deviation, and construct a histogram for these data.

2.) Construct a run chart

3.) Interpret the results
