An electronics retailer is developing a model for insurance policies on new cell phone purchases. It estimates that52% of customers never make a claim, 30% of customers require a small repair costing an average of $70, and18% of customers request a full refund costing $260. What is the long-term average cost the retailer should expectto pay to its customers per claim?
Diastolic blood pressure in adults is normally distributed with m = 80 mm Hg and s = 12 mm Hg. In a ran-dom sample of 300 adults, how many would be expected to have a diastolic blood pressure below 70 mm Hg?
An editorial in The New York Times on Sunday, June 4, 2011 discussed the redesigned fuel economy stickers to be required on new cars starting in 2013. Consider a new midsize Ford Fusion S model. At $4-a-gallon gas, annual fuel costs would be about $2,200 for 15,000 miles driven. ... And that’s for a car with a rated mileage of 34.9 m.p.g. (actual highway mileage, as with all vehicles, is lower, in this case about 27 m.p.g.). Industry clearly needs to do better. Did the Times use the rated or the actual mileage in its computation? In Canada, some multi-lane highways have a speed limit of 110 km/hour. Convert this speed to miles per hour, so you'll know how fast you may drive in Canada.
