Question 1:
Question 2:
A population of values has a normal distribution with μ=182.8 and σ=70.6. You intend to draw a random sample of size n=181. Find P23, which is the mean separating the bottom 23% means from the top 77% means. P23 (for sample means) = Enter your answers as numbers accurate to 1 decimal place. Answers obtained using exact z-scores or z scores rounded to 3 decimal places are accepted.
A distribution of values is normal with a mean of 60 and a standard deviation of 24 . From this distribution, you are drawing samples of size 12 . Find the interval containing the middle-most 66% 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.
