This problem is fill in the blank.  Just choose the correct answers.  Thank you for your help   A coin-operated coffee machine made by BIG Corporation was designed to discharge a mean of 7.3 ounces of coffee per cup. If it dispenses more than that on average, the corporation may lose money, and if it dispenses less, the customers may complain. Believing that the mean amount of coffee dispensed by the machine, μ, is less than 7.3 ounces, BIG plans to perform a statistical test of the claim that the machine is working as designed. Technicians gather a random sample of fill amounts and find that the mean of the sample is 7.1 ounces and that the standard deviation is 0.3 ounces. Based on this information, answer the questions below.   1.  What are the null hypothesis (H0) and the alternative hypothesis (H1) that should be used for the test? H0:  (choose one) less than, less than or equal to, greater than, greater than or equal to, equal to, or not equal to.      (choose one)      7.1…

Only parts B and C please. Thank you.

rue or False? Assume a researcher recruits 150 African American and Caucasian individuals taking warfarin to determine if there is a difference in the mean dosage of the medication needed to cause a decrease in their INR blood test. If the mean dosage for 75 Caucasian individuals required to get their INR blood test in range is 6.1 mg with a standard deviation of 1.7 mg and the mean dosage for 75 African American individuals required to get their INR blood test in range is 4.3 mg with a standard deviation of 0.9 mg, the z value obtained while calculating the test statistic is approximately 9.60.  True  False
