A manufacturing company measures the weight of boxes before shipping them to the customers. If the box weights have a population mean and standard deviation of 90 kg and 24 kg respectively, then based on a sample size of 36 boxes, the probability that the average weight of the boxes will be less than 84 kg is:

A manufacturing company measures the weight of boxes before shipping them to the customers. The box weights have a population mean and standard deviation of 43 lbs. and 12 lbs. respectively. Based on a sample size of 64 boxes, the probability that the average weight of the boxes will exceed 44.83 lbs. is ____. Use only the appropriate formula and/or statistical table in your textbook to answer this question. Report your answer to 4 decimal places, using conventional rounding rules....
A food company sells salmon to various customers. The mean weig discount outlet stores in pallets of 64 salmon. To forecast costs, t ht of the salmon is 31 lb with a standard deviation of 2 lbs. The company ships them to restaurants in boxes of 9 salmon, to grocery stores in cart ons of 36 salmon, and to iles ostmers. the shipping department needs to est mate the standard deviation of the mean weight of the salmon in each...
SHOW ALL WORK PLEASE I'LL RATE THUMBS UPS The State Department of Weights and Measures is responsible for making sure that commercial weighing and measuring devices, such as scales, are accurate so customers and businesses are not cheated. Periodically, employees of the department go to businesses and test their scales. For example, a dairy bottles milk in 1gallon containers. Suppose that if the filling process is working correctly, the mean volume of all gallon containers is 1.00 gallon is normally...
4. A lift has an occupancy warning of no more than 25 people and of total weight no more than 1950kg. For a population of users, suppose weights are normally distributed with mean 75kg and standard deviation 10kg (a) What is the probability that the total weight of a random sample of 25 people from the population exceeds 1950kg? (b) Calculate the probability that a random sample of 24 people sets the alarm off. (c) Suppose people carry things with...

part 1. You measure 24 dolphins' weights, and find they have a mean weight of 36 ounces. Assume the population standard deviation is 13.2 ounces. Based on this, construct a 95% confidence interval for the true population mean dolphin weight. Give your answers as decimals, to two places part 2.

A manufacturer produces 25pound lifting weights. The lowest actual weight is 24 pounds, and the highest is 26 pounds. Each weight is equally likely so the distribution of weights is uniform. A sample of 100 weights is taken. a. What is the distribution for the weights of one 25pound lifting weight? What is the mean and standard deviation? b. What is the distribution for the mean weight of 100 25pound lifting weights? c. Find the probability that the mean actual...
t a computer manufacturing company, the actual size of computer chips is normally distributed with a mean of 10 centimeter and a standard deviation of 2.1 centimeter. A random sample of 24 computer chips is taken. What is the probability that the sample 2. A mean will be between 10.95 and 11.05 centimeters? The personnel director of a large corporation wants to study absenteeism among clerical workers at the corporation's central office during the year. A random sample of 25...
