Fоr the upcоming summer Olympics in Pаris, Under Shield is develоping а new rаcing suit for the American swimming team. The typical suit worn at prior Olympic games had an average drag coefficient (Cd) of of 2.2.(Drag coefficient measures the resistance or friction of an object as it travels through air; the less drag, the better for our athletes.) A sample of twenty-five (25) of the new Under Shield swimsuits were tested, and the new suits had an average drag coefficient of 2.0, with a standard deviation of 0.39. Can Under Shield make the claim to the U.S. Olympic Committee that these new suits will perform better than the suits used in prior Olympic games? The required level of significance, α, is .01. 1. Provide the hypothesis test criteria: HO: μ [NullOperator] [Mu0] HA: μ [alteOperator] [Mu0A] 2. Critical value approach: Compare the test statistic of [TestStat] to the critical value of [CriticalValue] 3. P-value approach: Compare the p-value of [pValue] to α = .01 4. Conclusion: (Type either Accept or Reject): [AcceptReject] HO 5. What should the U.S. Olympic Swimming team do in regard to the new suits? (Business decision): [WDTM] 6. There is a "red flag" that the U.S. Olympic Committee should be aware of concerning this sample of the new suits when considering this proposal from Under Shield. What is that "red flag"? [RedFlag]
The prоductiоn line аt the Heinz ketchup fаctоry is cаlibrated to fill bottles of ketchup with no more than 24 ounces of ketchup in each container. We certainly do not want ketchup spilling onto the assembly line; that would be messy! In order to test how well the machinery is working, from one day's production of ketchup bottles filled, a sample of 50 bottles are selected and the contents of each container are measured. The most recent quality control check revealed a mean of 24.1 ounces per bottle, with a sample standard deviation of 0.3 ounces. Industry standards set the required level of significance, α, at .05. 1. Provide the hypothesis test criteria: HO: μ [NullOperator] [Mu0] HA: μ [alteOperator] [Mu0A] 2. Critical value approach: Compare the test statistic of [TestStat] to the critical value of [CriticalValue] 3. P-value approach: Compare the p-value of [pValue] to α = .05 4. Conclusion: (Type either Accept or Reject): [AcceptReject] HO 5. What does this mean? (Business decision): [WDTM]
