A population of values his normal distribution with men equal to 27.6 and standard deviation equal 39.4 do you intend to draw a
Alecsey [184]

Answer:

The mean of the distribution of sample means is 27.6        

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 27.6

Standard Deviation, σ = 39.4

We are given that the population is a bell shaped distribution that is a normal distribution.

Sample size, n = 173.

We have to find the mean of the distribution of sample means.

Central Limit theorem:

  • It states that the distribution of the sample means approximate the normal distribution as the sample size increases.
  • The mean of all samples from the same population will be approximately equal to the mean of the population.

Thus, we can write:

\mu_{\bar{x}} = \mu = 27.6

Thus, the mean of the distribution of sample means is 27.6

Can someone help me solve these three problems please??
Tasya [4]
I'll solve 21, and you then should be able to solve the rest on your own!

Since ADC is 135, that means that that whole angle is 135 degrees. In addition, since angles ADB and BDC add up to ADC, we get ADB+BDC=ADC=135=11x+9+7x=18x+9. Subtracting 9 from both sides, we get 126=18x. Dividing both sides by 18, we get x=7. Plugging that into 11x+9=BDC, we get 11*7+9=77+9=86

Solve equations: 3|x+4|=6<br><br> | = absolute value
Anestetic [448]

Absolute values are a way of finding a distant from zero, which means there will be 2 answers; one will be positive, and the other will be negative.

|<em>3x - 4</em>| = 5<em>and</em> |3<em>x - 4</em> = a^5 Because you need 2 answers, you have to make 5 positive and negative.

Another way to write this equation would be...

5=|3x-4|=—5

Now lets continue...

5=3x-4=—5

Add 4 to both sides...

9=3x=—1

Now divide by 3...

3=x= -1/3

So the solution is...

X={-1/3  3}
