A researcher collected data on the six randomly selected commercial suppliers for the US Department of Defense (DoD). Among other metrics, she recorded their experience, measured in years, to be 30, 10, 9, 10, 5 and 10 years. Assume that this sample satisfies the condition of a random sample from the population of DoD commercial suppliers. You want to make an argument: "On average, commercial suppliers of DoD have over 5 years of experience". Based on this information, answer the questions a-h below. (a) Formulate the appropriate null and alternative hypothesis for testing the claim. *Since Canvas does not allow to use special symbols in the answer options, I use mu to denote the population mean p, x-bar to denote the sample mean 7, and != as the operator + (not equal to) Null hypothesis HO: Alternative hypothesis HA: [Choose ] X-bar = 5 mu > 5 mu = 5 X-bar !=5 mu != 5 X-bar > 5 (a) Formulate the appropriate null and alternative hypothesis for testing the claim. *Since Canvas does not allow to use special symbols in the answer options, I use mu to denote the population mean pi, x-bar to denote the sample mean 2, and != as the operator + (not equal to) Null hypothesis HO: [ Choose Alternative hypothesis HA: [Choose ] X-bar = 5 mu > 5 mu = 5 X-bar !=5 mu != 5 X-bar > 5 D 7 1.5 pts
