A diet doctor claims Australians are, on average, overweight by
more than 10kg. To test this claim, a random sample of 100
Australians were weighed, and the difference between their actual
weight and their ideal weight was calculated and recorded.
The data are contained in the Excel file Weights.xlsx.
Use these data to test the doctor's claim at the 5% level of
significance.
