Answer: The standard deviation of the sampling distribution of M is equal to the standard deviation of the population divided by the square root of the sample size.
You can assume that the sampling distribution of M is normally distributed for any sample size.
Step-by-step explanation:
- According to the central limit theorem , if we have a population with mean
and standard deviation
, then if we take a sufficiently large random samples from the population with replacement , the distribution of the sample means will be approximately normally distributed. - When population is normally distributed , then the mean of the sampling distribution = Population mean

- Standard deviation of the sampling distribution =
, where
= standard deviation of the population , n= sample size.
So, the correct statements are:
- You can assume that the sampling distribution of M is normally distributed for any sample size.
- The standard deviation of the sampling distribution of M is equal to the standard deviation of the population divided by the square root of the sample size.
Answer:
47
Step-by-step explanation:
180 - 43 - 90
The GCF of 3 and 12 is 3, so divide both numbers by 3
3 / 3 = 1
12 / 3 = 4
So in simplest form is 1:4
Answer:
Step-by-step
sum of the adjacent angles of parallelogram is supplementary.
Therefore,
Q + R = 180°
4y+7 + 10y-37 = 180°
14y - 30° = 180°
14y = 210°
y = 210°/14
y = 15°
Could not found X in the question.
Answer:
he could buy 5 cookies and 7 brownies
Step-by-step explanation:
8.75 for the brownies and it is 3.75 for the cookies = 12.50
7*1.25=8.75 5*0.75= 3.75 equals 12.50 all together
he can't buy more than 12 cookies and brownies all together.
