A manufacturer fills soda bottles. Periodically the company tests to see if there is a difference between the mean amounts of soda put in bottles ofregular cola and diet cola. A random sample of 13 bottles of regular cola has a mean of 497.9 mL of soda with a standard deviation of 3.4 mL. Arandom sample of 11 bottles of diet cola has a mean of 502.6 mL of soda with a standard deviation of 4.3 mL. Test the claim that there is adifference between the mean fill levels for the two types of soda using a 0.05 level of significance. Assume that both populations are approximatelynormal and that the population variances are not equal since different machines are used to fill bottles of regular cola and diet cola. Let bottles ofregular cola be Population 1 and let bottles of diet cola be Population 2.Step 2 of 3: Compute the value of the test statistic.

Consider the following data: −11,−5,−5,−11,13,−11,−5−11,−5,−5,−11,13,−11,−5 Copy Data Step 2 of 3: Calculate the value of the sample standard deviation. Round your answer to one decimal place.
The Food and Drug Administration has determined that a substance called Melamine poses a health threat when it contaminates food. In fact, it poses a health threat even to dogs when it is in their food. Consequently, the FDA wants to monitor shipments of dog food imported into the country. From previous studies on dog food, the FDA knows that the population mean of Melamine in dog food is 8.0 grams in a 40 pound bag, with a population standard deviation of 1.5 grams. How likely would it be that a random sample of 36 40-pound bags of dog food would have a mean of more than of 8.4 grams of Melamine per bag? All bags have at least 8 grams 0.05 0.50 None of the bags will have less than 8 grams
The wildlife department has been feeding a special food to rainbow trout fingerlings in a pond. Based on a large number of observations, the distribution of trout weights is normally distributed with a mean of402.7grams and a standard deviation of12.8grams.

I have a distribution with mean zero and variance of 9. I sample 4 people from the population. What is my standard error? Round to 3 decimal points.
Scenario 38-5. Researchers are interested in the height of the average person in San Francisco, California. Using a random sample of 1,000 people, they find that the average height in the sample is 68 inches. (Hint: Be sure to calculate the Refer to Scenario 38-5. If the standard deviation of heights is 3 inches, we can be 95% confident that the true mean height of the population is between standard error of the estimate.) O O O O between 67.997 inches and 68.003 inches. between 67.905 inches and 68.095 inches. between 67.905 inches and 68 inches. between 68 inches and 68.095 inches.
