a. The point estimate of the married people that sleep well is = 0.6299. The confidence interval for the mean hours of sleep for those that have never been married but report good sleep is 0.6186, 0.6412
b. The point estimate of the number of hours for people that have never been married = 7.2257
95% confidence interval for the mean number of hours of sleep for those who have never been married = 7.2065, 7.2447
c. the estimated number of sleep for those that have never been married = 7.729 hours
a. The point estimate
[tex]P=\frac{Xp}{n}[/tex]
[tex]Xp = successes\\n = sample size\\[/tex]
Those who have never been married n = 7044
Xp = those who sleep for 7 hours at least
To get Xp, the excel function
Countif(range, criteria)
Countif(A:A, >=7)
This gives Xp = 4437
Point estimate =
[tex]\frac{4477}{7044}[/tex]
= 0.6299
The point estimate of the married people that sleep well is = 0.6299
At 95% interval of confidence,
α = 1-0.95 = 0.05
α/2 = 0.05/2 = 0.025
Z0.025 = 1.96 ( Use the standard probability normal table)
Margin of Error
=[tex]M.E = 1.96\sqrt \frac{0.6299(1-0.6299)}{7044} \\\\= 1.96\sqrt{0.000033} \\\\1.96*0.0057[/tex]
= 0.0113
The 95% confidence interval
= 0.6299 - 0.0113 , 0.6299 + 0.0113
= 0.6186, 0.6412
The confidence interval for the mean hours of sleep for those that have never been married is 0.6186, 0.6412
b. Sample mean
x = ∑x/n
x = number of sleep of the never been married
Mean is calculated using excel function
Average(range)
Average(a:a)
This gives the sample mean = 7.2257
The point estimate of the number of hours for people that have never been married = 7.2257
Standard deviation using excel =
Stdev(A:A) = 0.8211
[tex]Margin of error =1.96*\frac{0.8211}{\sqrt{7044} }[/tex]
= 0.0192
The confidence interval =
= 7.2257-0.0192, 7.2257+0.0192
= 7.2065, 7.2447
95% confidence interval for the mean number of hours of sleep for those who have never been married = 7.2065, 7.2447
c. From the available data, the mean number of sleep per day that is gotten from the 4437 people that are unmarried and sleep healthily for at least 7 hours = 34295.1
Mean = 34295.1/4437
= 7.729
the estimated number of sleep for those that have never been married = 7.729 hours

Identity 2 reasons why it is important for a young adult to establish credit.
Explanation:
Establishing credit is essential for young adults, as it involves supporting their financial needs in the long run.
Reason 1: Establishing credit reflects a borrower's creditworthiness.
When you apply for a credit card, acquire a vehicle through financing, and even renting an apartment or buying a home all involves the creditors looking at the timeliness of your payments. Credit cards or any type of loans are forms of debt (liabilities). Creditors are also in the business of making money. Thus, they want to make sure that they are loaning their funds to a trustworthy borrower.
The creditors try to determine whether you are only making minimum payments on your credit card, or if you're paying your debt in full by the due date. All of these factors reflect on your responsible use of finances and creditworthiness, which are the basis of your credit score as a borrower or debtor. If your're making your payments on time and are reasonably paying for your debt, then you're able to build up your credit history. Hence, the creditors will see you in a positive light the next time you apply for a loan. The higher your credit score, the lower your interest rates will be.
Reason 2: Employers run credit reports on job applicants.
Creditworthiness as a reflection of an individual's financial responsibility also has a positive bearing on how an employer views you as a prospective employee. Employers want to hire trustworthy and reliable individuals. Thus, financial responsibility is highly relevant, especially when you're applying for positions that involve handling money or finances as a part of your job.

Kiwi Airlines has fixed operating costs of $5.8 million, and its variable costs amount to 20 percent of sales revenue. The firm has $2 million in bonds outstanding with a coupon interest rate of 8 percent. Revenues for the firm are $8 million and the firm is in the 40 percent corporate income tax bracket. What is the firm's degree of financial leverage
Kiwi Airlines' degree of financial leverage is 1.36.
Data and Calculations:
Fixed operating costs = $5.8 million
Revenue = $8 million
Variable costs = 20% of sales = $1.6 million ($8 x 20%)
Earnings before interest and taxes = $600,000 ($8 - $5.8 - $1.6 million)
Bonds outstanding = $2 million
Coupon interest rate = 8%
Interest expense = $160,000 ($2,000,000 x 8%)
Earnings before taxes = $440,000 ($600,000 - $160,000)
Corporate income tax = 40%
Income Tax Expense = $176,000 ($440,000 x 40%)
Net Income = $264,000 ($440,000 - $176,000)
Degree of financial leverage = earnings before interest and taxes/earnings before taxes
= $600,000/$440,000
= 1.36
Thus, Kiwi Airlines' degree of financial leverage is 1.36.
