A population of values has a normal distribution
with μ=78.9μ=78.9 and σ=13.8σ=13.8. You intend to
draw a random sample of size n=61n=61.
Find the probability that a single randomly selected value is
between 78.7 and 84.4.
P(78.7 < X < 84.4)
= Incorrect
Find the probability that a sample of size n=61n=61 is
randomly selected with a mean between 78.7 and 84.4.
P(78.7 < M < 84.4)
= Incorrect
Enter your answers as numbers accurate to 4 decimal places. Answers
obtained using exact z-scores
or z-scores rounded to 3 decimal places are
accepted.
