Put the numeric value rounded to two decimal places in the first box and the correct units in the second
box.
f) What is the shape of the sampling distribution of the sample mean?
Select an answer
Why? Check all that apply:
On is at least 30
n is less than 30
population is normal
o is unknown
population is not normal
o is known
g) Find the probability that the sample mean blood pressure of the 25 randomly selected people in China is
less than 136.9 mmHg.
Round final answer to 4 decimal places.
DO NOT use the rounded standard deviation from part e in this computation.
Use the EXACT value of the standard deviation with the square root.
h) Find the probability that the sample mean blood pressure of the 25 randomly selected people in China is
more than 137.32 mmHg.
Round final answer to 4 decimal places.
DO NOT use the rounded standard deviation from part e in this computation.
