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. WEE' The lifespan of one randomty chosen component. 0 A. Normal 0 B. Binomial O 0. Neither
