Test plots in Yellowstone National Park were used to study tree reproduction of lodge pole pine. In plots of 50 square meters, the number of new lodge pole saplings was counted. In a given region, based on long observation, the population standard deviation is known to be o = 44 3aplings. , How many 50 square meter plots should be sampled in such a region to be 95% confident that the sample mean of the lodge pole saplings is within 10 saplings of the population mean u of lodge pole saplings in all 50 square meter plots in this area?
