Answer:
D. 68%
Step-by-step explanation:
The following statistics are given;
sample mean = 47%
s = 5% ; the sample standard deviation
n = 625 ; the sample size
The confidence interval for a population mean is given as;
sample mean ± z-score*
Substituting the above values we have;
47 ± z-score*
47 ± z-score*0.2
The confidence interval has been given as;
lower limit = 46.8%
upper limit = 47.2%
We can use any of these two values with the above expression to solve for the z-score. Using the lower limit we have the following equation;
47 - z-score*0.2 = 46.8
-z-score*0.2 = 46.8 - 47
-z-score*0.2 = -0.2
z-score = 1
The area of the standard normal curve between -1 and +1 will be the confidence level for the given confidence interval.
Pr( -1<Z<1 ) = 0.68 = 68%

Answer:
$117,380,000
Step-by-step explanation:
Stockholders' Equity section of the balance sheet
Paid in capital:
common stock $120 Par (500,000 Shares Authorized, 400,000 Shares Issued) = $120 * 400,000 = $48,000,000
Excess over par = $6,400,000
Paid in capital, common stock = $48,000,000 + $6,400,000 =$54,400,000
From sale of treasury stock = $4,500,000
Sum total paid-in capital = $54,400,000 + $4,500,000 = $58,900,000
Retained earnings =$63,680,000
Treasury stock (40,000 shares at cost) = $5,200,000
Total stockholders’ equity =$58,900,000 + $63,680,000 - $5,200,000
= $117,380,000
