Determine the probability (assuming normal distribution) that a light bulb would have a life expectancy less than 900 hours.
What will be an ideal response?
The value 900 is below the mean value and the z score corresponding to 900 is computed from
A = 0.1331. Therefore, the probability that a light bulb would have a life expectancy less than 900 hours is 0.5-0.1331 = 0.3669V
