Suppose the lives of light bulbs for a certain brand are normally distributed, with a mean life of 1900 hr and a standard deviation of 100 hr. Find the probability that a light bulb of that brand lasts between 1790 hr and 2060 hr. Click here to view page 1 of the standard normal table Click here to view page 2 of the standard normal table. The probability that a light bulb will last between 1790 hr and 2060 hr is (Type an integer or decimal rounded to four decimal places as needed.)
