Description
The Yonalasee tennis club has two systems to measure the speed of
a tennis ball. The local tennis pro suspects one system (Speed1)
consistently records faster speeds. To test her suspicions, she
sets up both systems and records the speeds of 12 serves (three
serves from each side of the court). The values are stored in the
data frame Tennis in the variables Speed1 and
Speed2. The recorded speeds are in kilometers per hour.source
