A machine that puts corn flakes in boxes is adjusted to put a consistent amount in each box with a standard deviation of 0.25 oz. If a random sample of 12 boxes gave a sample standard deviation of 0.28 oz, do these data support the claim that the standard deviation has increased and the machine needs to be brought back into adjustment? (use significance=0.5) Assume the population is approximately normally

A machine that puts corn flakes into boxes is adjusted to put an average of 15 ounces into each box, with a standard deviation of 0.25 ounce. The distribution of ounces per box has a normal distribution. If a random sample of 12 boxes had a sample standard deviation of 0.38 ounce, does this data support the claim that the standard deviation has increased and the machine needs to be adjusted. Use a 0.01 level of significance. This problem is...

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...

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 deviation of 0.15 fluid Ounces. Assume that the syrup content of a beverage is normally distributed. Then, to check the claim that the syrup content per beverage is about one ounce, we use the following test...
