3 Seedless green grapes are sold in mess bags at Winn Dixie

3) Seedless green grapes are sold in mess bags at Winn Dixie and typically consist of 3-5 bunches per bag. Suppose the weight of these bags follows a normal distribution with a mean and standard deviation based on the table to the right. Determine the probability that a randomly selected bag will contain the value indicated below? The randomly selected bag will contain 26.0 ounces

µ = 27.2 = 8

Solution

HERE MEAN = 27.2 AND STD DEV = 8

Hence P(x >=26) = P(z >0.15) = [area to the left of 0.15] = 0.5596
