Say you have 50 samples, each with 15 puppies. All have been rated in regards to cuteness. You are asked by the kennel association to calculate the Standard Error of the Mean for them. They just couldn’t do it and they need it for accreditation purposes. However, they were able to tell you that the mean for one of the samples was 8.4, and it’s standard deviation was 1.3, while the range was 5. So, please calculate the Standard Error of Mean, which is:
