1) Six racing snails are arguing about how to increase their crawling speed. One of them, Sam, claims that he can move faster if he stretches as far as possible with each slither. A second, Simon, claims that snail speed is increased if a snail takes shorter and, therefore, faster Slithers. A third snail, Sadie, argues that speed can only be increased if a racing snail actually leaps forward between Slithers. The snails agree that they will race three times, trying each of these approaches. Their 1 meter race times, in minutes, are as follows: Snail Stretch Small Slithers Leap Sam 10 9 1 1 Susan 8 8 12 Sarah 7 9 13 Simon 9 l 1 l 1 Sadie 9 12 14 Sanford 8 1 3 l 5 a) Is there an overall signicant difference between mean race times using the three different techniques? (a = .05) (7 marks) b) Regardless of your results in part a), do the appropriate analysis to determine if there are any differences among the experimental conditions. ((1 = .05)
