The weights of ice cream cartons are normally distributed with a mean weight of 20 ounces and a standard deviation of 0.5 ounces. You randomly select 25 cartons. What is the probability that their mean weight is greater than 20.06 ounces? 1. 0.274 2. 0.452 3. 0.548 4. 0.726
1) The weights of the fish in a certain lake are normally distributed with a mean of 20 lb and a 1). standard deviation of 9. If 9 fish are randomly selected, draw, label and shade the normal curve, find the z-scores, and find the probability that the mean weight will be between 17.6 and 23.6 lb. Draw, label, and shade: Z-scores: P(17.6<x< 23.6)
The weight X of babies (of a fixed age) is normally distributed with mean μ = 212 ounces and standard deviation σ = 25 ounces. Doctors would also be concerned (not necessarily alarmed) if a baby is among the upper 10 percent in weight. Find the cut-off weight u, above which the doctors will be concerned. The weight X of salmon caught in a river is normally distributed with mean μ = 24 pounds and standard deviation σ = 6...

112 pts) 7. If the average weight of a bag of pretzels is normally distributed with a mean of 16 ounces and a standard deviation of 3 ounce find the probability that a randomly selected bag of pretzels will contain between 15.6 and 16.4 ounces. Refer to the table.
The weights of employees in a large company are normally distributed with a mean of 88 kg and a standard deviation of 21 kg. What is the probability that the weight of a randomly selected employee is 89kg?
The weights of a certain brand of candies are normally distributed with a mean weight of 0.8604 g and a standard deviation of 0.052 g. A sample of these candies came from a package containing 459 candies, and the package label stated that the net weight is 391.99. (If every package has 459 candies, the moon weight of the candies 391.9 must exceed 250 =0.8539 g for the net contents to weigh at least 391.99.) a. If 1 candy is...
The weights of a certain brand of candies are normally distributed with a mean weight of 0.8547 g and a standard deviation of 0.0523 g. A sample of these candies came from a package containing 454 candies, and the package label stated that the net weight is 387.4 g. (if every package has 454 candies, the mean weight of the candies must exceed 387.4/454= 0.8532 g for the net contents to weigh at least 387.4 g) a. If 1 candy...
