Refer to the data on percentage iron in 66 bulk specimens of Chilean lumpy iron ore, Exercise 2.79. The data are saved in the LUMPYORE file. Assess whether the data are approximately normal.

Data From Exercise 2.79:

Lumpy iron ore. Sixty-six bulk specimens of Chilean  lumpy iron ore (95% particle size, 150 millimeters) were randomly sampled from a 35,325-long-ton shipload of ore, and the percentage of iron in each ore specimen was determined. The data are shown in the table.
