1. A random sample of the liquid content (in fluid ounces) in beverage cans is shown...
the amount of liquid in cans of a cola beverage has mean value 16 ounces and standard deviation of 0.143 ounces (a) what is the probability that a randomly selected can of that cola beverage contains at least 15.9 ounces? (b) what is the probability that the mean amount x of beverage in a random sample of 34 such cans is at least 16.1 ounces
2. A machine that fills beverage cans is supposed to put 12 ounces of beverage in each can. Following are the amounts measured in a simple random sample of eight cans. 11.96 12.10 12.04 12.13 11.98 12.05 11.91 12.03 A dotplot of the sample data suggests that the population is approximately normal. Perform a hypothesis test to determine whether the mean volume differs from 12 ounces. Use the a= 0.05 level of significance. (a) State the null and alternate hypotheses....
(1 point) a) A random sample of 13 cans of peach halves has a mean weight of 16 ounces and standard deviation of 0.4 ounces. Find a 90% confidence interval for a true standard deviation of the weights of all cans of peach halves. Confidence interval: b) What would be the confidence interval for a true standard deviation if the sample size was 45? Confidence interval:(
How much is in that can? A machine that fills beverage cans is supposed to put 12 ounces of beverage in each can. Following are the amounts measured in a simple random sample of eight cans. 12.09 11.98 12.16 12.03 12.12 12.20 12.10 12.18 Perform a hypothesis test to determine whether the mean volume differs from 12 ounces. Use the a-0.01 level of significance and the critical value method.
2. A postmix beverage machine is adjusted to release a certain amount of syrup into a chamber where it is mixed with carbonated water. A random sample of 25 beverages was found to have a mean syrup content of 1.05 fluid ounces and a standard devia- tion of 0.15 fluid Ounces. Assume that the syrup content of a beverage is normally distributed (a) [1] Give a point estimate for the mean syrup content in a beverage. Give also the standard...
A postmix beverage machine is adjusted to release a certain amount of syrup into a chamber where it is mixed with carbonated water. A random sample of 25 beverages was found to have a mean syrup content of t= 1.17 fluid Ounces and the sample standard deviation is s = 0.015 fluid Ounces. Find a 95% two-sided confidence interval on the mean volume of syrup dispensed. Assume population is approximately normally distributed. beverages was found to have mangrup content 863...

Soda six-packs Most soda cans list the volume of soda as 12 fluid ounces. As with all process, some variation occurs when filling soda cans. Suppose that a company knows this and tries to over-fill cans a bit, so that the actual volume of soda in a can follows a normal distribution with mean 12.1 fluid ounces and standard deviation .15 fluid ounces. a) What proportion of soda cans filled by this process will contain less than 12 fluid ounces?...
A person measures the contents of 36 pop cans and finds the mean content to be 12.1 fluid ounces with a standard deviation of 0.2 ounces. Construct a 99 percent confidence interval for the average fluid content of a can.E) [12.035, 12.165] A) [12.019, 12.181] B) [12.009, 12.191] C) [12.022, 12.178] D) [12.014, 12.186]
The number of beverage cans produced each hour from a vending machine is normally distributed with a standard deviation of 8.6. For a random sample of 12 hours, the average number of beverage cans produced was 326.0. Construct a 99% confidence interval for the population mean number of beverage cans produced per hour.
