A store sells "16-ounce" boxes of Captain Crisp cereal. A random sample of 12 boxes was taken and weighed. The average weight of cereal was 15.93 ounces with the sample standard deviation 0.135 ounces. The company that makes Captain Crisp cereal claims that the average weight of cereal in a box is at least 16 ounces. Assume the weight of cereal in a box is normally distributed. We wish to test H 0 : μ 16 vs H 1 :...
Weights of cereal in 16 ounce boxes are normally distributed with a mean of 16 ounces...
Weights of cereal in 16 ounce boxes are normally distributed with a mean of 16 ounces and a standard deviation of 0.12 ounce. Respond to the following: a)What is the probability that a cereal box selected at random will have at least 15.95 ounces? b)What is the probability that the mean of a sample of 16 boxes will be at least 15.95 ounces? c)In a production of 10,000 boxes, how many would you expect to be below 15.95 ounces? d)The...

A cereal company claims that mean weight of cereal boxes is at most 16.1 ounces. Suppose that a plant manager wishes to test whether the true mean weight of cereal boxes is greater than 16.1 ounces. Suppose that for this problem the population standard deviation is 0.4 and the population distribution is normal. The manager obtain a random sample of size 25 and finds a mean of 16.3 ounces. Using p value approach test the claim of company at significance...

13 A package-filling device is set to fill cereal boxes with a mean weight of 24 ounces of cereal per box. The standard deviation of the amount actually put into boxes is known to be 0.55 ounces. A random sample of 25 filled boxes is taken, and each is weighted, yielding a mean weight of 24.25 ounces. Test at 0.02 significance level to determine whether the device is working properly. (6 points).

A random sample of 64 bags of white cheddar popcorn weighed, on average, 5.45 ounces with a standard deviation of 0.25 ounce. Test the null hypothesis that μ=5.5 ounces against the alternative hypothesis, μ<5.5 ounces, at the 0.05 level of significance. What is the p-value? a. 0.025 b. 0.05 c. 0.0548 d. 0.0274

A cereal box filling machine is designed to release an amount of 12 ounces of cereal into each box, and the machine’s manufacturer wants to know of any departure from this setting. The engineers at the factory randomly sample 100 boxes of cereal and find a sample mean of 12.25 ounces. If we know from previous research that the population is normally distributed with a standard deviation of 1.51 ounces, is there evidence that the mean amount of cereal in...

A local bottler in Hawaii wishes to ensure that an average of 16 ounces of passion fruit juice is used to fill each bottle. In order to analyze the accuracy of the bottling process, he takes a random sample of 48 bottles. The mean weight of the passion fruit juice in thee sample is 15.80 ounces. Assume that the population standard deviation is 0.8 ounce. (You may find It useful to reference the appropriate table: z table or t table...
