Suppose the weights of Farmer Carl's potatoes are normally distributed with a mean of 9 ounces and a standard deviation of 1.1 ounces. Round your answers to 4 decimal places.
If one potato is randomly selected, find the probability that it weighs less than 10 ounces.
Solution :
Given that ,
mean = = 9
standard deviation = = 1.1
P(X< 10) = P[(X- ) / < (10 -9) /1.1 ]
= P(z <0.91 )
Using z table
= 0.8186

Help with this issue - how to solve? Potatoes: Suppose the weights of Farmer Carl's potatoes are normally distributed with a mean of 8.5 ounces and a standard deviation of 1.3 ounces. (a) Carl only wants to sell the best potatoes to his friends and neighbors at the farmer's market. According to weight, this means he wants to sell only those potatoes that are among the heaviest 20%. What is the minimum weight required to be brought to the farmer's...

The weights of ice cream cartons are normally distributed with a mean weight of 7 ounces and a standard deviation of 0.3 ounce. (a) What is the probability that a randomly selected carton has a weight greater than 7.12 ounces? (b) A sample of 25 cartons is randomly selected. What is the probability that their mean weight is greater than 7.12 ounces? (a) The probability is (Round to four decimal places as needed.)
The weights of ice cream cartons are normally distributed with a mean weight of 11 ounces and a standard deviation of 0.5 ounce. (a) What is the probability that a randomly selected carton has a weight greater than 11.17 ounces? (b) A sample of 16 cartons is randomly selected. What is the probability that their mean weight is greater than 11.17 ounces?

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...
