A soft drink company produces bottles of cola that are supposed to contain 10 ounces. When the bottling machine is working correctly, the number of fluid ounces per bottle is in fact normally distributed with mean 10 ounces and standard deviation 0.42 ounces. A customer buys nine bottles of this type of cola. What is the probability that the average volume of cola in the nine bottles is more than 9.7 ounces but less than 10.2 ounces? (A) 0.9074 (B)...

A bottling company uses a filling machine to fill plastic bottles with a popular cola. The bottles are supposed to contain 300 milliliters (ml). In fact, the contents vary according to a normal distribution with mean µ=303 ml and standard deviation σ= 5 ml What is the probability that an individual bottle contains greater than 305 ml? What is the probability that the sample mean of 100 bottles is less than 302 ml?

#8. Bottles of a certain lubricant are designed to contain 6.0 oz. The amount in the container is actually a normal random variable with mean 6.1 oz and s.d. .08 oz. To check whether the machine doing the filling is actually meeting specs fill volumes of a sample of 4 bottles are measured. Call these Xi, X2, X3, X4; assume that they are independen. The true mean fill volume μ, is estim ated by tak ng (a) Is Y an...

please and thanks :))
A machine fills bottles with 48 fluid ounces of liquid. The quality-control manager determines that the fill levels are normally distributed with a mean of 48 ounces and a standard deviation of 0.38 ounces. He has an engineer recalibrate the machine in an attempt to lower the standard deviation. After the recalibration, the quality control manager randomly selects 19 bottles from the line and determines that the standard deviation is 0.34 ounces. Using a level of...

1. Bottles of a popular soda are supposed to contain 300 milliliters of soda. The volume of soda in the bottles distributes approximately normally. An inspector measured the contents of six randomly selected bottles. The results, in milliliters, were 299.4, 297.7, 301.0, 298.9, 300.2, and 297.0. At a 10% level of significance, would you say the manufacturer is meeting their obligation that the bottles contain 300 milliliters of soda? Use technology to find the mean and standard deviation of the...
