Question:
The number of hours before a battery must be replaced in Wellbuilt watches is normally distributed with a mean of 1,900 hours and a standard deviation of 145 hours. What proportion of watch batteries fail before 1,600 hours? Suppose that during the next six months, more than 50% fail before 1,600 hours. From a problem-sensing perspective, what might you conclude?
