A soft-drink vending machine can be regulated to ensure that it dispenses an average of 6 oz. of soft drink per glass. If the ounces dispensed per glass are normally distributed with a standard deviation of 0.3 oz., find the probability for a sample of 5 bottles, that the machine will average more then 6.3 ounces.

A vending machine automatically pours soft drinks into cups. The amount of soft drink dispensed into a cup is normally distributed with a mean of 7.7 ounces and standard deviation of 0.3 ounce. Examine the figure below and answer the following questions. a.) Estimate the probability that the machine will overflow and 8-ounce cup. (Round your answer to two decimal places.) b.) Estimate the probability that the machine will not overflow an 8-ounce cup. (Round your answer to two decimal...
5. Problem 5: A bottling machine can be regulated so that it discharges an average of pi ounces per bottle. It has been observed that the amount of fill dispensed by the machine is normally distributed with a = 1 ounce. A sample of n = 9 filled bottles is randomly selected from the output of the machine on a given day, and the ounces of fill are measured for each. Find the probability that the sample mean will be...
A soft-drink machine is regulated to discharge an average of 7 ounce per cup. The amount of drink is considered normally distributed with a standard deviation of 0.5 ounce. What is the probability that a cup chosen at random will contain 7. C2 7,8 a) between 6.5,andR2 ounce? b) exactly 7.0 ounce? c) less than 7.3 ounce? d) If the cups hold exactly 8 ounces, what is the probability that a cup will overflow? e) What should be cup's size...
A soft-drink machine at a steak house is regulated so that the amount of drink dispensed is approximately normally distributed with a mean of 210 milliliters and a standard deviation of 12 milliliters. The machine is checked periodically by taking a sample of 9 drinks and computing the average content. If x falls in the interval 204<x<216, the machine is thought to be operating satisfactorily; otherwise, the owner concludes that u # 210 milliliters. Complete parts (a) and (b) below....

. (18 points) Many students have complained that the soft drink vending machine in the student recreation room (A) dispenses a different amount of soda than the machine in the faculty lounge (B). To test this belief, a student randomly sampled several servings from each machine and carefully measured them, with the results shown in the following table: MachineT Sample Size Sample MeanSample Standard Deviation 2 6 10 Assume that the amounts dispensed by both machines are independent and r...
The amounts a soft drink machine is designed to dispense for each drink are normally? distributed, with a mean of 11.9 fluid ounces and a standard deviation of 0.2 fluid ounce. A drink is randomly selected. ?(a) Find the probability that the drink is less than 11.7 fluid ounces. ? (b) Find the probability that the drink is between 11.4 and 11.7 fluid ounces. ?(c) Find the probability that the drink is more than 12.3 fluid ounces. Can this be...

(c) Find the probability that the drink is more than 12.4 fluid ounces. Can this be considered...
1. A vending machine that dispenses coffee into cups must fill the cups with 7.8 oz of liquid. Before selling the vending machine to a college or business, the company tests the machine to be sure it is dispensing an average amount of 7.8 oz of coffee. A sample of 20 amounts is shown here. Assume that the amount of coffee dispensed is normally distributed. 7.78 7.79 7.82 7.82 7.87 7.84 Ounces Dispensed 7.80 7.80 7.83 7.85 7.82 7.78 7.75...
