In a recent year, Washington State public school students taking a mathematics assessment test had a mean score of 276.1 and a s

Oksi-84 [34.3K]

Answer:

a) $\mu_{\bar x} =\mu = 276.1$

$\sigma_{\bar x} =\frac{\sigma}{\sqrt{n}}=\frac{34.4}{\sqrt{64}}=4.3$

b) From the central limit theorem we know that the distribution for the sample mean $\bar X$ is given by:

$\bar X \sim N(\mu=276.1, \frac{\sigma}{\sqrt{n}}=4.3)$

c) $P(\bar X \geq 285)=P(Z\geq \frac{285-276.1}{4.3}=2.070)$

$P(Z\geq2.070)=1-P(Z$

Step-by-step explanation:

Let X the random variable the represent the scores for the test analyzed. We know that:

$\mu=E(X) = 276.1 , \sigma=Sd(X) = 34.4$

And we select a sample size of 64.

The central limit theorem states that "if we have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed. This will hold true regardless of whether the source population is normal or skewed, provided the sample size is sufficiently large".

Part a

For this case the mean and standard error for the sample mean would be given by:

$\mu_{\bar x} =\mu = 276.1$

$\sigma_{\bar x} =\frac{\sigma}{\sqrt{n}}=\frac{34.4}{\sqrt{64}}=4.3$

Part b

From the central limit theorem we know that the distribution for the sample mean $\bar X$ is given by:

$\bar X \sim N(\mu=276.1, \frac{\sigma}{\sqrt{n}}=4.3)$

Part c

For this case we want this probability:

$P(\bar X \geq 285)$

And we can use the z score defined as:

$z=\frac{\bar x -\mu}{\sigma_{\bar x}}$

And using this we got:

$P(\bar X \geq 285)=P(Z\geq \frac{285-276.1}{4.3}=2.070)$

And using a calculator, excel or the normal standard table we have that:

$P(Z\geq2.070)=1-P(Z$

A clothing manufacturer makes 1,500 pairs of jeans. They ship their jeans to stores in packages of 36. How many full packages wi

Crazy boy [7]

Answer:

a) How many full packages will be used to ship the jeans?

41 packages

b) How many jeans are left over?

24 Jeans

Step-by-step explanation:

We are told that a manufacturer: made 1500 Jeans and is shipping them in packages of 36.

Hence, the number of packages of 36 he can send out to stores is calculated as:

1500÷ 36

= 41.666666667

In whole number packages = 41 packages

Hence, 41 full packages would be used to ship the jeans.

The number of Jeans left behind is

1500 - (41 × 36)

= 1500 - 1476

= 24 Jeans

Find the cost of sending a telegram which has 34words if the cost of the first ten words is4050$and the cost of each extra word

Stells [14]

Answer:

The final cost would be $42,780 for sending a 34 word telegram.

Step-by-step explanation:

1. $4050*10= $40,500

2. 34-10=24

3. 24*$95= $2,280

4. $40,500+$2,280= $42,780

Hope this helps! :)

IM having trouble trying to solve this problem

Assoli18 [71]

Answer:

You would have approximately 201 insects.

Step-by-step explanation:

To calculate the final population of the insects, you need to first insert the values of each variable you know into the equation. The initial population at time $t=0$ would be 100 insects, the rate of population growth coverted to decimal form would be 0.1, and the elapsed time since time $t=0$ is 7 days. Now the new equation would be $P = 100(e)^{0.1*7}$ .
