Question 4: K-Log produces cereals that are sold in boxes labeled to contain 390 grams. If the cereal content is below 390 grams, K-Log may invite auditor’s scrutiny. Filling much more than 390 grams costs the company since it essentially means giving away more of the product. Accordingly, K-Log has set specification limits at 400 10 grams for the weight of cereal boxes. Currently a filling machine fills the boxes. The boxes weigh on average 380 grams with a standard...

1. Lloyd’s Cereal Company packages cereal in 1-pound boxes (1 pound = 16 ounces). It is assumed that the amount of cereal per box varies according to a normal distribution with a mean of 1 pound and a standard deviation of 0.08 pound. One box is selected at random from the production line every hour, and if the weight is less than 14 ounces, the machine is adjusted to increase the amount of cereal dispensed. The probability that the amount...

The packaging process in a breakfast cereal company has been adjusted so that an average of μ = 13.0 oz of cereal is placed in each package. The standard deviation of the actual net weight is σ = 0.1 oz and the distribution of weights is known to follow the normal probability distribution. 1. what proportion of cereal packages contain more than 12.9 oz? 2. Suppose 25 cereal boxes are chosen at random, what is the mean weight of all...

Q3: A nutritionist believes that 12-ounce boxes of cereal should contain an average of 1.2 ounces of bran. She suspects that a popular cereal has a different mean bran content. She carefully analyzes the contents of a random sample of twenty 12-ounce boxes of the cereal and finds that the mean bran content is 1.16 ounces. It is known that the standard deviation of the bran content of all such boxes of cereal is 0.08. Do the data provide sufficient...

1) A sample of cereal boxes is randomly selected and the sugar contents (grams of sugar per gram of cereal) are recorded. Those amounts are summarized with these statistics: n = 16, ?̅ = 0.295g, s = 0.168g. Use a 0.05 significance level to test the claim that the mean of all cereals is less than 0.3g. Section 7-6 Problem Testing a Claim about a Standard Deviation a ) Use a 0.05 significance level to test the claim that heights...

Reginald Brown, an inspector from the Department of Weights and Measures, weighed 15 eighteen-ounce cereal boxes of corn flakes. He found their mean weight to be 17.8 ounces with a standard deviation of 0.4 ounces. Are the cereal boxes lighter than they should be? Using significance level of 0.01, perform a hypothesis test. Step #1: State the hypotheses and identify the claim. Step #2: What is the test value? Step #3: What kind of test is being run? Step #4:...
