What price do farmers get for their seedless watermelon crops? In a recent month, a simple random sample of 32 farming regions gave a sample mean of $12.15 per 100 pounds of seedless watermelon. Assumer that σ=$1.57σ=$1.57 per 100 pounds.
Find a 90% confidence interval for the population mean price (per 100 pounds) that farmers in this region get for their seedless watermelon crop. (Round answers to two decimal places.)
margin of error: $ per 100 pounds
lower limit: $ per 100 pounds
upper limit: $ per 100 pounds
What conditions were met for the above calculations to be valid? (Select all that apply.)
Find the sample size necessary for a 90% confidence level with an margin of error E=0.35E=0.35 for the mean price per 100 pounds of seedless watermelon. (Increase to the next whole number.)
If a farmer brings in 10 tons of seedless watermelon to a market, find a 90% confidence interval for the population mean cash value for 10 tons of seedless watermelon. Note: 1 ton = 2000 pounds. (Round your answers to two decimal places.)
