The weight of potato chips in a medium-size bag is stated to be 10 ounces. The amount that the packaging machine puts in these bags is believed to have a normal model with a mean of 10.1 ounces and a standard deviation of 0.07 ounces.

a) What fraction of all bags sold are underweight?

b) Some of the chips are sold in "bargain packs" of 5 bags. What's the probability that none of the 5 is underweight?

c) What's the probability that the mean weight of the 5 bags is below the stated amount?

d) What's the probability that the mean weight of a 24-bag case of potato chips is below 10 ounces?

Jamie believes that a 9 ounce bag of potato chips does not really contain 9 ounces...

Jamie believes that a 9 ounce bag of potato chips does not really contain 9 ounces of chips. It is known that all potato chip bags are normally distributed with a standard deviation of 1 ounce. He wants to test this hypothesis at the 5% level of significance. He takes a sample of 40 bags of chips and finds the average amount of potato chips to be 10.5 ounces. What should Jamie’s conclusion be using the p-value approach? Be sure...

A manufacturer of potato chips would like to know whether its bag filling machine works correctly at the 409 gram setting. Based on a 21 bag sample where the mean is 417 grams and the standard deviation is 26, is there sufficient evidence at the 0.1 level that the bags are overfilled? Assume the population distribution is approximately normal. Step 1 of 5: State the null and alternative hypotheses. Step 2 of 5: Find the value of the test statistic....
