Scenario 2: Electronic Component The manufacturer of a certain electronic component claims that they are designed to last just slightly more than 4 years because they believe that customers typically replace their device before then. Based on information provided by the company, the components should last a mean of 4.24 years with a standard deviation of 0.45 years. For this scenario, assume the lifespans of this component follow a normal distribution. Use this scenario for problems 9 - 13. 9. We will consider several random variables for this scenario in the following problems. For each random variable below, determine if it follows a normal distribution, a binomial distribution, or neither. (2 pt ea) A. Normal B. Binomial C. Neither The lifespan of one randomly chosen component. In a group of 35 randomly chosen components, the number of them which last more than 4 years. The sample mean lifespan for groups of 20 randomly chosen components. The sample mean lifespan for groups of 35 randomly chosen components. The number of components that last more than 4.5 years from a group of 10 independent components.
