How sample to be accurate within ten peaches per tree

Reference no: EM13125191

A study of peach trees showed that the average number of peaches per tree was 1000. The standard deviation of the population is 100. A scientist wishes to find the 98% confidence interval for the mean number of peaches per tree. How many trees does she need to sample to be accurate within 10 peaches per tree?
