Answer:

A. The mean is 0.51 and the standard deviation is 0.0142.

Step-by-step explanation:

When we know the mean of the population (0.51), we don't need to estimate the mean of the sampling distribution from the mean of a sample (0.63).

Then, the mean of the sampling distribution is equal to the mean of the population (0.51).

The standard deviation is calculated as:

\sigma_p=\sqrt{\frac{\pi(1-\pi)}{N} \frac{x}{y} }= \sqrt{\frac{0.51(1-0.51)}{1231} }=0.0142

What is the value of x?
Oliga [24]

Answer:

<u>x = 14</u>

Step-by-step explanation:

4x + (2x + 6) = 90

6x + 6 = 90

subtract both sides by 6:

6x + 6 <em>- 6 </em>=<em> </em>90 <em>- 6</em>

6x = 84

divide both sides by 6

6x/6 = 84/6

x = 14

double check:

4*14 + (2*14 + 6) = 90

56 + 28 + 6 = 90

Have a nice day!
