A cereal company claims that the mean weight of the cereal in its packets is more than 14 oz. The weights (in oz) of the cereal in a random sample of 8 cereal packets are listed below. You may assume the sample data comes from a population that follows a normal distribution. Using a 0.05 significance level, test the companies claim. State the null hypothesis H0. State the alternative hypothesis H1. What is the test statistic? State the alpha level....

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...

9. A potato chip manufacturer claims that the weights of its potato chips are normally distributed...
9. A potato chip manufacturer claims that the weights of its potato chips are normally distributed with a mean of 10 ounces per bag. The Department of Consumer Protection takes a random sample of 23 bags of potato chips from a shipment to test whether or not they really weigh 10 ounces. If the sample has mean weight of 9.85 ounces and standard deviation of 0.3 ounce, can you conclude that a bag of potato chips does not weigh 10...
