Natasha records the price for a gallon of home-heating oil from 20 randomly selected providers in her region on May 15.
She does it again with another 20 randomly selected providers on November 15. The results (in dollars) are shown in the
accompanying samples. Each date had one provider that had a price of $2.879 per gallon. Is the $2.879 price per gallon
more unusual to occur on May 15 or November 15?

A street light is mounted at the top of a 15-ft-tall pole. A man 6 feet tall walks away from the pole with a speed of 7 ft/s along a straight path. How fast (in ft/s) is the tip of his shadow moving when he is 40 feet from the pole?
