2x + 6 + 3x + 12 = 33

5x + 18 = 33

5x = 33-18

Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.9 years with a

Bas_tet [7]

Answer:

5.9 years.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1-p)}{n}}$

In this question:

Mean of the population is $\mu = 5.9$

If a sampling distribution is created using samples of the ages at which 69 children begin reading, what would be the mean of the sampling distribution of sample means?

By the Central Limit Theorem, the same population mean, of 5.9 years.

Answer:

in today's market supply and demand fluctuates. for example the recent demand for apple air pods. They came out in 2016 but were not very popular,But with the sudden increase in demand the amount sold has increased by 75 percent from 2017 to 2018. this could be graphed using the equation. f(x)=1.75x+16

with each unit on the graph equaling 1 million on the y axis

and the amount of years along the x but you must start at 16 along the x axis

in 2017 there was 16 million air pods sold and in December 2018 28 million were sold during that year
