Answer:
C.The mean of the sampling distribution is always
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , a large sample size, of at least 30, can be approximated to a normal distribution with mean and standard deviation .
So
A is wrong, because it is
B is wrong, you need a sample size of at least 30.
So the correct answer is:
C.The mean of the sampling distribution is always
2/14 = 1/7
then 1/7×1400 = 200
Answer:
c.
Step-by-step explanation:
Ralph’s calculation is correct, he will have to pay $9,280 in federal taxes this year.
The volume of a cone whose radius is 3 1 / 2 cm and vertical height is 24 cm is 307.72 cm³
<h3>Volume of a cone</h3>
The volume of a cone can be represented as follows:
volume = 1 / 3 πr²h
where
Therefore,
r = 3 1 / 2 cm = 7 / 2 cm
h = 24 cm
Hence,
volume = 1 / 3 × π × (7 / 2 )² × 24
volume of a cone = 1 / 3 × π × 49 / 4 × 24
volume of the cone = 1 / 3 × π × 1176 / 4
volume of the cone = 1176 / 12 π
volume of the cone = 98π
volume of the cone = 307.72 cm³
