A distribution of values is normal with a mean of 100 and a standard deviation of 12. From this distribution, you are drawing samples of size 11. Find the interval containing the middle-most 74% of sample means: Enter your answer using interval notation. In this context, either inclusive or exclusive intervals would be acceptable. Your numbers should be accurate to 1 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.
