Answer:

n = 3.6

Step-by-step explanation:

Start by removing the brackets on both sides.

28 - 14n = -2n -2n - 8

Combine like terms on the right.

28 - 14n = - 4n - 8  

Add 14n to both sides.

28 -14n + 14n = -4n + 14n -8

Combine like terms

28 = 10n - 8  

Add 8 to both sides

28 + 8 = 10n - 8 + 8

Combine like terms

36 = 10n

Divide by 10

36/10 = 10n/10

n = 3.6

n=3.6

Do the distributive property to both sides then add 14n to -4n and get 10n then add 8 to both sides to get 36, the u have 10n=36 then divide each side by 10, 10/10 cancel each other then 36/10 = 3.6 so N=3.6

The Corporate Lawyer, a magazine for corporate lawyers, reported that out of 200 firms with employee stock ownership plans, 150
tiny-mole [99]

Answer:

The 90% confidence interval for the population proportion of all such firms with this as the primary motivation is (69.96%, 80.04%).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the z-score that has a p-value of 1 - \frac{\alpha}{2}.

The Corporate Lawyer, a magazine for corporate lawyers, reported that out of 200 firms with employee stock ownership plans, 150 indicated that the primary reason for setting up the plan was tax related.

This means that n = 200, \pi = \frac{150}{200} = 0.75

90% confidence level

So \alpha = 0.1, z is the value of Z that has a p-value of 1 - \frac{0.}{2} = 0.975, so Z = 1.645.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.75 - 1.645\sqrt{\frac{0.75*0.25}{200}} = 0.6996

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.75 + 1.645\sqrt{\frac{0.75*0.25}{200}} = 0.8004

As percent:

0.6996*100% = 69.96%

0.8004*100% = 80.04%.

The 90% confidence interval for the population proportion of all such firms with this as the primary motivation is (69.96%, 80.04%).
