Using technology, find the mean and standard deviation. Round to the nearest tenth, if necessary. The mean of the data is The standard deviation of the data is Use Chebyshev's theorem to find an interval centered about the mean number of deaths from UV radiation in which you would expect at least 75% of the numbers to fall. At least 75% of the numbers of deaths will fall between and Use Chebyshev's theorem to find an interval centered about the mean number of deaths from UV radiation in which you would expect at least 88.9% of the numbers to fall. At least 88.9% of the numbers of deaths fall between and
