Based on information provided by the company, the components should last a mean of 4.24 years with a standard deviation of 0.46 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. The number of components that last more than 4.5 years from a group of 10 independent components. 0 A. Nonnai O B. Binomial O C. Neither
