The summer monsoon rains bring 80% of India's rainfall and are essential for the country's agriculture. Records going back more than a century show that the amount of monsoon rainfall varies from year to year according to a distribution that is approximately Normal with mean 852852 millimeters (mm) and standard deviation 82 mm. Use the 68‑95‑99.7 rule to answer the questions. (a) Between what values do the monsoon rains fall in the middle 95%95% of all years? between 164 and 1540 mm between 770 and 934 mm between 606 and 1098 mm between 688 and 1016 mm (b) How small are the monsoon rains in the driest 2.5% of all years? less than 770 mm less than 606 mm less than 21.3 mm less than 688mm
