Now letâs see what we get when we do the math. The mean of this new data set would be the sum of the values ($690,000) divided by the number of values (11). This gives you a mean or average salary for the accounting department of $62,727.
Forget Orville Wright and his brother Wilbur. Start thinking instead of Alberto Santos Dumont, the Brazilian pioneer aviator and the man who really invented the aeroplane. That is the attitude here in Brazil, as the country prepares to celebrate the centenary tomorrow of the world's first powered flight.
Wright Brothers. Aviation was really born on the sand dunes at Kitty Hawk, N.C., on Dec. 17, 1903. On that day Orville Wright crawled between the wings of the plane he and his brother Wilbur had built, opened the throttle of their homemade 12-horsepower engine, and took to the air. He covered 120 feet in 12 seconds. In a fourth attempt that day, Wilbur stayed up 59 seconds and covered 852 feet. These were the first controlled, sustained flights in a power-driven airplane. More on the Wright Brothers and the early days of flight. Charles Lindbergh. Lindbergh made the world's first nonstop solo flight across the Atlantic. Early on May 20, 1927, he took off in The Spirit of St. Louis, traveling 3,610 miles from Long Island, N.Y., to Paris, France.
