USE THE INFORMATION BELOW TO ANSWER QUESTIONS 22 THRU 23 In recent years home lighting technology has changed dramatically due to the development of Light Emitting Diode (LED ) bulbs. Although previously used mainly in traffic lights and although LED bulbs are more expensive than incandescent bulbs, they use approximately 90% less energy and they last up to 25 times longer than incandescent bulbs. It has been estimated that the average home saves $250 per year using LED bulbs rather than incandescent bulbs. One popular manufacturer of LED bulbs claim that nearly all of their 75-watt LEDs will last for more than 25,000 hours. D Question 22 1 pts Suppose that a small company purchases 200 of these 75-watt LEDs with a guarantee that 95% of them will last for more than 25,000 hours. Assuming the guarantee is correct, what is the probability that at least 190 of them will last for more than 25,000 hours?
