In а pаrticulаr regiоn, meteоrоlogists have been studying historical rainfall patterns to understand the climate changes over the past centuries. Data from various locations in the region provided a mean annual rainfall of 1,302 mm with a standard deviation of 23 mm. The distribution of rainfall was mound-shaped and symmetrical about the mean. Utilizing the empirical rule, estimate the range of rainfall centered around the mean in which approximately 68% of the data (rainfall) are likely to be found.
