Compute smaller variability in bull-riding time

Assignment Help Basic Statistics
Reference no: EM131751400

Question: Sports and Leisure Bull riding has become a very popular rodeo sport-the action is fast and dangerous. A bull ride is scored by two judges; one actually rates the bull, while the other evaluates the rider. The variance in bull-riding time tends to be large, approximately 22.5 seconds2. A random sample of 37 bull rides was selected over an entire rodeo season. The sample variance in riding times was s2 = 15.6 seconds2. Smaller variability in bull-riding time translates to a more monotonous, unexciting rodeo. Is there any evidence that bull riding has become less exciting? Assume normality and use a = 0.05.
