PetSmart is interested in how much dogs like a new treat they have developed. The compare their new treat to the other major treats on the market that have an average likeability score of 10. (likeability is how many seconds it takes the dogs to eat the treat; lower numbers means they like it more because they are eating faster). PetSmart gets a sample of the first 100 dogs that enter the store on Saturday and has the dogs try their new treat. These 100 dogs eats the treats in 8.7 seconds with a standard deviation of 2.03 seconds. What test statistic ( inferential statistic) is most appropriate to determine whether the new treat is liked more than the other treats on the market
