The value that distinguishes the lowest 25% of data from the highest 75% is -0.00235. Previous concepts: Normal distribution, which describes a "probability distribution that is balanced around the mean, indicating that data close to the mean occur more frequently than those further away from it". The Z-score is "a statistical measurement relating a value to the mean of a set of values, in terms of its distance in standard deviations from the mean". To solve the problem, let X represent the variable of interest in a population; we know the distribution for X is given by:... We want to find a value a to satisfy the condition:... Both conditions here are equivalent. We can apply the Z-score again to find the value a. The figure shows that the z value meeting the condition with 0.25 of the area to the left and 0.75 to the right is z = -0.674. Therefore, P(Z < -0.674) = 0.25 and P(z > -0.674) = 0.75. We can use condition (b) previously to derive... We know the z value that satisfies the equation, so we can proceed to solve for a, which gives us... Thus, the value that separates the lower 25% of data from the upper 75% is -0.00235.
Answer:
Explanation:
A)
The formula for regression is,
ln(Cell Phone Subscribers) = -820.894 + 0.411704 Year
or,
Percentage of Cell Phone Subscribers = exp(-820.894 + 0.411704 Year)
For the year 2005,
Percentage of Cell Phone Subscribers = exp(-820.894 + 0.411704 * 2005)
= 96.79%
B)
The significance of the slope has a p-value close to 0 (0.000). Hence, the model holds statistical significance and its predictions are very reliable.
This scenario exemplifies Agency conflict. It occurs when someone has the authority to make decisions on behalf of an entire organization. In this case, shareholders support an acquisition offer while the board of directors chooses to decline it.
Answer:
$46,000.
Explanation:
To determine the retained earnings as of the end of 2015, we must first assess the total dividend that will be distributed to shareholders, and then combine the net income from 2015 with the leftover retained earnings from the conclusion of 2014 (after the distribution of 2014's dividend in March 2015) to arrive at the retained earnings figure for the close of 2015.
Total dividend on March 2015 = 0.7 x 100,000 = 70,000
Retained Earnings as of the end of 2015 = 94,000 - 70,000 + 22,000 = 46,000.
Answer: The answers are:
A) $200,000.
B) $258,881.
C) $177,399.
Explanation: The values for the financial calculator are:
Future value = $ 200.000.
Payment = $ 200,000 x 0.10 = $ 20,000.
n = 5 x 2 = 10. (Semesters in 5 years).
YTM = (a) 10 percent, (b) 6 percent, and (c) 12 percent.
A) Present value = $200,000.
B) Present value = $258,881.
C) Present value = $177,399.
