A distribution of values is normal with a mean of 160 and a standard deviation of 15. From this distribution, you are drawing samples of size 23.
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 2-scores rounded to 3 decimal places are accepted.
