A beverage manufacturer has been accused of helping customers by overfilling its bottles. There are reports on social media of bottles containing more than advertised. A consumer advocacy panel investigated whether the manufacturer was indeed helping customers by overfilling the bottles; they found a random sample of bottles contained an average of 8 oz. The bottles are labeled 7.79 oz. (a) Which hypotheses should the consumer panel test? H0: Ha: (b) Which value of a would make it harder for the consumer panel to conclude the manufacturer is helping its customers? a= 0.01 a= 0.05 a= 0.10

Step 1
79 oz, while the alternative hypothesis (Ha) should state that the average bottle volume is greater than 7.79 oz. Show more…

The manager of a soda company knows his bottles are supposed to be filled with 20 ounces of soda. A random sample of 10 bottles is taken and they were found to have a mean of 20.8 ounces and a standard deviation of 1.3 ounces. Is there evidence that the soda company is overfilling the bottles? Use a = .01. b. Construct a 96% confidence interval for the mean amount of soda in the bottles.

A bottling company produces bottles that hold 10 ounces of liquid. Periodically, the company gets complaints that their bottles are not holding enough liquid. To test this claim, the bottling company randomly samples 81 bottles and finds the average amount of liquid held by the bottles is 9.915 ounces with a standard deviation of 0.45 ounce. Suppose the p-value of this test is 0.045. State the proper conclusion. At α = 0.025, reject the null hypothesis. At α = 0.035, accept the null hypothesis. At α = 0.085, fail to reject the null hypothesis. At α = 0.05, reject the null hypothesis.

A new shampoo is being test-marketed. Many 16-ounce bottles were mailed out at random to potential customers in the hope that the customers will return an enclosed questionnaire. Out of the 1,200 returned questionnaires, 975 indicated that they like the shampoo and will consider buying it when it becomes available on the market. Perform a hypothesis test to determine if the proportion of potential customers is at most 70 percent. Use a level of significance of 0.025. a) State the null and alternate hypothesis b) Find the z-score c) State the conclusion.
