Question
1) A well-designed and safe workplace can contribute greatly to increased productivity. IT is especially important that workers not be asked to perform tasks, such as lifting, that exceeds their capabilities. A particular company is interested in determining whether or not the true maximum weight lift of their employees exceeds 25. This company randomly selects five individuals and computes their maximum weight lift. The sample average is 27.54 and the standard deviation of the sample is 5.47. a. Define the parameter of interest. b. What are the appropriate null and alternative hypotheses? c. Compute the test statistic. d. Circle Lef/Right/Between/Outside. Also, enter a value for (a), and enter a value for (b) or (c) (but not both). Left Right Between Outside d.f.: (a) t-value: (b) probability: (c) The p-value for this hypothesis test turns out to be 0.18. Please give your conclusion at the 5% level of significance. e.Explanation / Answer
