## What price do farmers get for the peach crops? in the third week of June, a random sample of 40 farming regions gave a sample mean of \$6.88 per basket. assume that the standard deviation is known to be \$1.92 per basket. find a 90% confidence interval for the population mean price per basket that farmers in this region get for their peach crop

Given:Sample size, n = 40Sample mean, xb = \$6.88Population std. deviation, σ = \$1.92 (known)Confidence interval = 90% Assume normal distribution for the population.The confidence interval is(xb + 1.645*(σ/√n), xb – 1.645*(σ/√n)= (6.88 + (1.645*1.92)/√40, 6.88 – (1.645*1.92)/√40)= (7.38, 6.38) Answer: The 90% confidence interval is (7.38, 6.38)
