12.14 Chapter 12 Review Questions

A study (de Lucas, Balidan, Neiva, and Denadai, 2000) tested whether wearing wetsuits influences swimming velocity. Twelve competitive swimmers and triathletes swam 1500M at maximum speed twice each — once wearing a wetsuit, and once wearing a regular bathing suit. The order of the trials was randomized. Each time, the maximum velocity in meters/sec of the swimmer was recorded.

The Wetsuits data frame has 12 observations on the following four variables.

  • Wetsuit Maximum swim velocity (m/sec) when wearing a wetsuit.
  • NoWetsuit Maximum swim velocity (m/sec) when wearing a regular bathing suit
  • Gender Gender of swimmer: F or M
  • Type Type of athlete: swimmer or triathlete
