Question:
When a fair die is rolled many times, the outcomes of 1, 2, 3, 4, 5, and 6 are equally likely, so the mean of the outcomes should be 3.5. The author drilled holes into a die and loaded it by inserting lead weights, then rolled it 16 times to obtain a mean of 2.9375. Assume that the standard deviation of the outcomes is 1.7078, which is the standard deviation for a fair die. Use a 0.05 significance level to test the claim that outcomes from the loaded die have a mean different from the value of 3.5 expected with a fair die. Is there anything about the sample data suggesting that the methods of this section should not be used?

I graduated in 2018 with a Bachelor of Science degree in Psychology from Dalubhasaan ng Lungsod ng San Pablo. I tutored students in classes and out of classes. I use a variety of strategies to tutor students that include: lecture, discussions about the subject matter, problem solving examples using the principles of the subject matter being discussed in class , homework assignments that are directed towards reinforcing what we learn in class , and detailed practice problems help students to master a concept. I also do thorough research on Internet resources or textbooks so that I know what students need to learn in order to master what is being taught in class .
