A manufacturer claims that the calling range (in feet) of its 900-MHz cordless telephone is greater than that of its leading competitor. A sample of 13 phones from the manufacturer had a mean range of 1060 feet with a standard deviation of 37 feet. A sample of 18 similar phones from its competitor had a mean range of 1050 feet with a standard deviation of 39 feet. Do the results support the manufacturer's claim? Let μ1 be the true mean...
