4) What price do farmers get for their watermelon crops? In the third week in July, a random sample of 40 farming regions gave a sample mean of x = $6.88 per 100 pounds of watermelon. Assume that o is known to be $1.92 per 100 pounds (Reference: Agricultural Statistics, U.S. Department of Agriculture). know the popu a) Find a 90% confidence interval for the population mean price (per 100 pounds) that farmers in this region get for their watermelon crop. What is the margin of error? bution with with mean . For samples of siz b) Find the sample size necessary for a 90% confidence level with maximal margin of error E = 0.3 for the mean price per 100 pounds of watermelon. about the mean but has thicker tails than the eedom increase, the distribution
