A machine set to fill soup cans with a mean of 20 ounces and a standard deviation of 0.1 ounces. A random sample of 34 cans has a mean of 20.02 ounces. Should the machine be reset?
No, the probability of this outcome at 0.122, would be considered usual, so there is no problem
No the probability of this outcome at 0.421 would be considered usual, so there is no problem
Yes, the probability of this outcome at 0.878 would be considered unusual, so the machine should be reset

A machine used to fill gallon-sized paint cans is regulated so that the amount of paint dispensed has a mean of 120 ounces and a standard deviation of 0.30 ounce You randomly select 40 cans and carefully measure the contents. The sample mean of the cans is 119.9 ounces. Does the machine need to be reset? Explain your reasoning it is that you would have randomly sampled 40 cans with a mean equal to 119.9 ounces, because it within the...

Soft drink cans are filled by an automated filling machine and the standard deviation is 0.5 fluid ounce. Assume that the fill volumes of the cans are independent, normal random variables. Round your answers to four decimal places (e.g. 98.7654). What is the standard deviation of the average fill volume of 100 cans? If the mean fill volume 12.1 ounces, what is the probability that the average fill volume of the 100 cans is less than 12 fluid ounces? What...

Round your answers to four decimal places (e.g. 98.7654). If the mean fill volume is 12.1 fluid ounces, what should the standard deviation of fill volume equal so that the probability that the average of 100 cans is less than 12 fluid ounces is 0.005?
