Write a function double mysqrt( double x ) which computes the
value of the square root of x using
the bisection method. First you need to set the left and right
bounds for x. If 0<x<1 then lt = x
and rt = 1 and the sqrt(x) is somewhere in between. If x > 1
then lt = 1 and rt = x and sqrt(x)
is somewhere in between. In a loop you need to compute the mid
value between lt and rt and
compare the mid square with x. Depending on this comparison, you
would need to set either lt or
rt to the mid. The loop executes as long as fabs(rt-lt) > ERR .
You can set the const double ERR =
1-10. The function needs to return the mid.
In the main function use a loop to read a double, then print is
square root in 2 ways: one using
cmath’s sqrt function and the other using mysqrt. Of course, the
code is correct if the 2 values
from the functions are very close to eachother. The loop terminates
when the user enters q.

In a separate column, determine the percent of each quality cost as compared to the total quality costs by dividing individual quality cost categories by the total quality cost. In another column, determine the percent of each quality cost classification as compared to total sales by dividing individual quality cost classes by the total sales amount. Total all columns. Remember that the Percent of total quality cost column should total to 100%.

Use this scenario to answer questions below.
The Collins Research Crew (CRC) is interested in examining the number of vape/smoking stores (i.e. stores that sell vaping and cigarette/cigar smoking products) in low-income neighborhoods compared to other types of neighborhoods. CRC's research question is, "Do low-income neighborhoods have more vape/smoke shops than other types of neighborhoods?" Low-income neighborhoods were defined as those where the median household income is less than the U.S. federal poverty line. Non-low-income neighborhoods are those that the median household income is greater than the U.S. federal poverty line.
CRC employed a team of undergraduate researchers to go out and count the number of vape/smoke shops in a random selection of low-income and non-low-income neighborhoods. They define the population as all neighborhoods in King County.
They found a significant difference in the number of vape/smoke shops across neighborhoods. Specifically, low-income neighborhoods had a greater number of vape/smoke shops compared to non-low-income neighborhoods.
Match the null hypothesis, directional hypothesis, and non-directional hypothesis with their most appropriate statement.
Null Hypothesis
[ Choose ]
There is a relationship between the average number of vape/smoke shops and neighborhood type..
There is no relationship between the number of vape/smoke shops and neighborhood type.
Low-income neighborhoods have more vape/smoke shops than non-low-income neighborhoods.average.
Directional Hypothesis
[ Choose ]
There is a relationship between the average number of vape/smoke shops and neighborhood type..
There is no relationship between the number of vape/smoke shops and neighborhood type.
Low-income neighborhoods have more vape/smoke shops than non-low-income neighborhoods.average.
Non-directional hypothesis
[ Choose ]
There is a relationship between the average number of vape/smoke shops and neighborhood type..
There is no relationship between the number of vape/smoke shops and neighborhood type.
Low-income neighborhoods have more vape/smoke shops than non-low-income neighborhoods.average.
Given the research question asked in the scenario above, the best research hypothesis is a non-directional hypothesis.
True OR False
"Specifically, low-income neighborhoods had a greater number of vape/smoke shops compared to non-low-income neighborhoods." What is this sentence indicating?
A. Low-income people vape/smoke at higher levels than the average King County resident
B. Any difference is due to chance and not some systematic influence
C. Any difference is due to some systematic influence and not by chance
D. There is no difference in the number of vape/smoke shops

In 2017, Keenan Company paid dividends totaling $3,600,000 on net income of $10.8 million. Note that 2017 was a normal year and that for the past 10 years, earnings have grown at a constant rate of 10%. However, in 2018, earnings are expected to jump to $14.4 million and the firm expects to have profitable investment opportunities of $8.4 million. It is predicted that Keenan will not be able to maintain the 2018 level of earnings growth because the high 2018 earnings level is attributable to an exceptionally profitable new product line introduced that year. After 2018, the company will return to its previous 10% growth rate. Keenan’s target capital structure is 40% debt and 60% equity.
a. Calculate Keenan’s total dividends for 2018 assuming that it follows each of the following policies: 1. Its 2018 dividend payment is set to force dividends to grow at the long-run growth rate in earnings. 2. It continues the 2017 dividend payout ratio. 3. It uses a pure residual dividend policy (40% of the $8.4 million investment is financed with debt and 60% with common equity). 4. It employs a regular-dividend-plus-extras policy, with the regular dividend being based on the long-run growth rate and the extra dividend being set according to the residual dividend policy.
b. Which of the preceding policies would you recommend? Restrict your choices to the ones listed but justify your answer.
c. Assume that investors expect Keenan to pay total dividends of $9,000,000 in 2018 and to have the dividend grow at 10% after 2018. The stock’s total market value is $180 million. What is the company’s cost of equity?
d. What is Keenan’s long-run average return on equity?
e. Does a 2018 dividend of $9,000,000 seem reasonable in view of your answers to parts c and d? If not, should the dividend be higher or lower? Explain your answer.
