The phenomenon of handedness has been extensively studied in human populations. The percentages of adults who are right-handed, left-handed, and ambidextrous are well documented. What is not so well-known is that a similar phenomenon is present in other (cuter, fuzzier) animals. Dogs, for example, can be either right-pawed or left-pawed. In a random sample of 200 beagles, it was found that 55 were left-pawed and in a random sample of 200 collies 40 were left-pawed. Can we conclude that there is a statistically significant difference in the proportion of left-pawed beagles and collies? Use a significance level of a = 0.05.
