If someone will explain how to work these problems out, that'll help me a ton!
A weight loss program claims their patients loose an average of 3 pounds during the first month of the program but a consumer group believes the number is higher than that. A random sample of 8 program participants showed the following weight loss at the end of 1 month:
4.1 3.7 3.1 2.8 3.9 3.2 4.5 4.3
What is the correct decision about the claim at a .05 significance level?
