A large set of test scores has mean 60 and standard deviation 18. if each score is doubled, and then 5 is subtracted from the result, the mean and standard deviation is, " mean = 115; standard deviation = 36".mean = 2 x 60 -5 = 120 -5 = 115
standard deviation = 2 x18 = 36

The mean refers to the average and is figured as the entirety of all the results from the example partitioned by the aggregate number of events. 
The standard deviation (SD)refers to a measure that is utilized to evaluate the amount of variation or dispersion of a set of data values.A low standard deviation shows that the information directs incline toward be near the mean of the set, while an exclusive expectation deviation or high standard deviation demonstrates that the information brings up spread out finished a more extensive scope or range of values.
