Wild Cheetahs have an average speed of 60 miles per hour and standard deviation of 8.0 miles per hour. In a safari setting, the wild life conservationists measured the speeds of 36 cheetahs and found their average speed 58 miles per hour. At 10% significance level, find out whether the data provide sufficient evidence that the restrictions in safari setting has or has not changed the agility / average speed of cheetahs from their wild cousins?
