Can standard distrubution be used to describe the data set? See attached.

Note:
(c) 3(j) -- This should have asked you for Q=800 cvs in April (not January) since I didn't give you any January data. Further, my answers were for a January set of data that I was playing with. For the April data (your HW), I think the Ans: P=13.3% and T = 7.5/yr.

Solution Summary

A given data set is analyzed to see if a gaussian distribution can be used to describe it.

Solution Preview

See attached for data.

To determine if there are outliers, you can look for the lowest value and the highest value. Then find the absolute value of (sample value - mean)/standard deviation. If this is greater than 3, then the value can be regarded as an outlier. In your data set, the lowest value (92) = 1.3 and the highest (954) = 1.95. Neither of these are greater than 3, so we cannot ...
