Interval at 95% confidence = p+/- Z sqrt (p(1-p)/n)
Upper interval => 0.68=p+1.96 sqrt (p(1-p)/n)
Lower interval => 0.52=p-1.96 sqrt (p(1-p)/n)
Putting sqrt term to be "q"
0.68=p+1.96q
0.52=p-1.96q
Adding the two equations to solve for p (proportion of 150 adults rootng for North high school);
1.2 = 2p => p=0.6

B. is a democratic leadership
Answer:
To determine the closing balance of retained earnings
Explanation:
First and foremost, retained earnings are an important part of the shareholders' equity. In a bid to ascertain the correct position of total shareholders' equity at year-end, it is important that a statement of retained earnings reconciling the opening retained with net income and dividends declared during the year is prepared.
The balance at the end of the year is the total accumulated earnings which have not been distributed to shareholders as dividends or which may be used to finance projects that increase shareholders' wealth
Answer:
The profit maximizing output level declines by 2.5 units and the price rises by $100.
Explanation:
In a monopoly market the inverse demand curve is given as,
P = 1,200 - 40Q
The marginal cost of production of the last unit is $200.
The total revenue is
= 
= 
The marginal revenue of the last unit is
= 
= 1,200 - 80Q
At equilibrium the marginal revenue is equal to marginal price,
MR = MC
1,200 - 80Q = 200
80Q = 1,000
Q = 12.5
Putting the value of Q in the inverse demand function,
P = 
P = $700
Now, if the marginal cost rises to $400,
At equilibrium the marginal revenue is equal to marginal price,
MR = MC
1,200 - 80Q = 400
80Q = 800
Q = 10
Putting the value of Q in the inverse demand function,
P = 
P = $800
