QUESTION 27 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 0.46 years. For this scenario, assume the lifespans of this component follow a normal distribution. Use this scenario for problems 9 - 13. 11. The company considers a component to be "successful" if it lasts longer than the warranty period before failing. They estimate that about 69.9% of components last more than 4 years. They find a random group of 10 components that were sold and count the number of them which were "successful," lasting more than 4 years. b. What is the standard deviation for the number of these 10 components that will last more than 4 years? Round your answer to two decimal places. QUESTION 28
