What price do farmers get for their watermelon crops? In the third week of July , a random sample of 40 farmers of the regions got a sample mean = $12 per 100 pounds of watermelons . Assume that standard deviation is known to be $2 per 100 pounds . Please include graphs and show work a) Find a 99% confidence interval for the population mean price (per 100 pounds) that farmersin this region get for their watermelon crops.Data: X =;O =drawrb) Find the sample size necessary for a 90% confidence level with maximal margin of errorE=0.8 for the mean price per 100 pounds of watermelons.anGuNameDRIA
