Boxes are labeled as containing 600 g of cereal. The machine filling the boxes produces weights that are normally distributed with standard deviation 8 g. (a) If the target weight is 600 g, what is the probability that the machine produces a box with less than 585 g of cereal? (Round your answer to three decimal places.)

Boxes are labeled as containing 400 g of cereal. The machine filling the boxes produces weights that are normally distributed with standard deviation 12 g. (a) If the target weight is 400 g, what is the probability that the machine produces a box with less than 375 g of cereal? (Round your answer to three decimal places.) (b) Suppose a law states that no more than 10% of a manufacturer's cereal boxes can contain less than the stated weight of...

The amount of cereal that can be poured into a small bowl varies with a mean of 1.5 ounces and a standard deviation of 0.3 ounce. A large bowl holds a mean of 2.5 ounces with a standard deviation of 0.4 ounce. A student opens a new box of cereal and pours one large and one small bowl. Suppose that the amount of cereal the manufacturer puts in the boxes is a random variable with a mean of 16.2 ounces...

A machine that is programmed to package 5.60 pounds of cereal is being tested for its accuracy. In a sample of 100 cereal boxes, the sample mean filling weight is calculated as 5.69 pounds. The population standard deviation is known to be 0.09 pound. [You may find it useful to reference the z table.] a-1. Identify the relevant parameter of interest for these quantitative data. The parameter of interest is the proportion filling weight of all cereal packages. The parameter...
