A diet doctor claims that the average Australian is more than 5kg overweight. To test this claim, a random sample of 50 Australians were weighed, and the difference between their actual weight and their ideal weight was calculated. The mean and the standard deviation of that difference were 6.5 and 2.2 kg, respectively. Can we conclude, with α = 0.05, that enough evidence exists to show that the doctor’s claim is true?
