Answer:

67%

Test for 2 Independent means

Explanation:

Given that:

Average Female earning per week in sample = $346.98

Average Male earning per week in sample = $517.70

Female earning in percent of male earning :

(Female earning / male earning) × 100%

(346.98 / 517.70) * 100%

0.6702337 * 100%

67.02%

= 67%

Testing whether or not the difference in weekly earning by males and female can be conducted by testing the difference in sample means of both males and females by taking the two different samples as being independent.

Usually :

Null hypothesis : H0 : m1 - m2 = 0

Alternative hypothesis : H1 : m1 - m2 ≠ 0

Randall's has 28,000 shares of stock outstanding with a par value of $1 per share. The market value is $13 per share. The balanc
a_sh-v [17]

Answer: $38,200

Explanation:

There are 28,000 Outstanding shares with a $13 market value.

That means that in total they are valued at,

= 28,000 * 13

= $364,000

The firm announced a 15% dividend so we take 15% of the total amount.

= 15% * 364,000

= $54,600

$54,600 is the total amount they will pay as dividends.

Dividends are taken from the Retained Earnings meaning that the balance in Retained earnings is therefore,

= $92,800 - $54,600

= $38,200

$38,200 will be the balance in the retained earnings account after the dividend.
