6- A study is hold for two types of light bulbs. Length of their lives in hours was measured and other conditions were kept constant. 50 experiments were conducted for light bulb-A and it was detected that the average length of life of it is 725 hours with the 10 hours standard deviation while 100 experiments were held for light bulb-B with the result of 800 hours average length of life and 50 hours standard deviation. If µA and pB are population means of life lengths of light bulb A and B respectively, find %90 confidence interval of pB-µA. a) (73.376, 73.624) b) (30.589, 119.411) C) (66.453, 83.547) d) (68.341, 81.659) e) (73.928, 76.072) Leave blank
