Suppose that the current American president claims that the American population gives the current US president an approval score of 7 (on a scale of 1 to 10).
A researcher has doubts about this claim and conducts a random survey among 121 American respondents. This sample shows that the average approval score is 6.5 (st.dev. = 1.8).
What is the standard error of the sampling distribution of the
average approval score?
