Please give numerical measures not percentage and round to the three decimal places. Thank you.

The data from data349.dat contains information on 78 seventh-grade students. We want to know how well each of IQ score and self-concept score predicts GPA using least-squares regression. We also want to know which of these explanatory variables predicts GPA better. Give numerical measures that answer these questions. (Round your answers to three decimal places.) (Regressor: IQ) R 2 Incorrect: (Regressor: Self-Concept) R 2 29% IWhich variable is the better predictor? IQ

Self Concept

Please use the percentage of sales method and the ratio method where appropriate to

forecast 2018E financial statements using the 2017 data. Use formulas to do all

calculations of the forecast estimates and use the iteration formula to determine the

interest expense and amount of debt at the same time.

All assumptions should be included.

At the beginning of 2017, Student Copy anticipated a substantial increase in sales.

Despite good sales the company experienced a shortage of cash and found it needed to

increase its short term borrowing to $500,000.

To do this it had to change banks as its current line of credit was $300,000. The new line

of credit required that it pay off all of its notes payables also and to maintain is

accounts payables at 10 days outstanding. This way it would be able to take all of its

purchase discounts which are 2/10 net 30.

There will be additions to property, plant and equipment as there is a need for

capacity to increase to support this increase in sales. In addition, the company is

trying to keep its days sales outstanding at 30 days and a minimum cash balance as

100,000.

Sales are predicted to increase from $4,519,000 to $5,000,000.

Using the percentage of sales method and ratio method to develop pro forma balance

sheet and income statements for 2018 to determine the amount of BANK DEBT required

to support this sales increase.

Coupon payments are fixed, but the percentage return that investors receive varies based on market conditions. This percentage returned is referred to as a yield.

1. A bond’s yield to maturity (YTM) is the percentage return that it is expected to generate if the bond is assumed to be held until it matures. Calculating a bond’s YTM requires you to make several assumptions. Which of the following is one of these assumptions?

The bond has an early redemption feature.

The bond will not be called.

Consider the following case of Blue Moose Home Builders Inc.:

Blue Moose Home Builders Inc. has 9% annual coupon bonds that are callable and have 18 years left until maturity. The bonds have a par value of $1,000, and their current market price is $1100.35. However, Blue Moose Home Builders Inc. may call the bonds in eight years at a call price of $1,060.

What are the YTM and yield to call (YTC) on bonds:

2. Blue Moose Home Builders Inc.’s bonds have a yield-to-maturity (YTM) of _______ and a yield-to-call (YTC) of ________ .

3. If interest rates are expected to remain constant, what is the best estimate of the remaining life left for Blue Moose Home Builders Inc.’s bonds?

5 years

8 years

10 years

13 years

4. If Blue Moose Home Builders Inc. issued new bonds today, what coupon rate must the bonds have to be issued at par? ________

1.

Which of the following bonds would have the highest percentage change in value if all interest rates in the economy decrease by 1%?

Group of answer choices

20-year, zero coupon bond.

20-year, 5% coupon bond.

10-year, zero coupon bond.

1-year, 10% coupon bond.

20-year, 10% coupon bond.

Suppose you are signing a loan contract of $65,000 at an interest rate of 8.5%. You must make 5 equal payments at the end of the year for 5 years. How much would you still owe at the end of the first year, after you make the first payment?

Answer just the dollar amount without the + or - sign. Round to the nearest dollar.

3.

A public company's bonds have a $1,000 par value, mature in 25 years, pay interest semiannually, and sell at a price of $750. The nominal yield to maturity is 9.25%. What is the bond's nominal coupon interest rate?

Answer just the number without the % sign. Round to two decimal places.

Your percentage of body fat by weight is an important indicator of your general physical condition. For people in good health it should be between 10 and 15%. One way of determining this percentage is to measure your average body density. This can be done by weighing yourself underwater when you have completely exhaled. You can do this in your friendly neighbourhood pool by placing a kitchen scale on the bottom (one that is not damaged by being under water) and submerging yourself onto it when you have deeply exhaled. (You might want to use a snorkel if you are uncomfortable doing this trick.) You can then calculate your body density from the formula,  

D = W/(W-Ww)

where W is your normal weight and W_w is your weight underwater. (This formula assumes the density of water is one. If you are mathematically inclined and know a little about the physics of buoyancy from a high-school physics course you can easily derive this formula.) If as a result of such an experiment a 75 kg person is found to weigh 4.2 kg underwater, what is that person's body density?

Professionals who determine body fat by this method have developed the following mathematical relationship between percentage of body fat f and average body density D:

f = 100 x (4.20/D - 3.81)

What is the percentage of body fat in the person of the previous part?

A researcher wishes to estimate the percentage of adults who support abolishing the penny. What size sample should be obtained if he wishes the estimate to be within 4 percentage points with 99​% confidence if (a) he uses a previous estimate of 22​%?   (b) he does not use any prior​ estimates?

Part II To calculate the percentage of calories (kcal) derived from each of the energy nutrients when the total number of calories is known, divide the calories from each nutrient by the total number of calories, and multiply by 100. (3 x 5 points each = 15 points) Example: A person consumed 600 kcal from CHO, 360 kcal from Fat and 240 kcal from Pro. How many kcal did she consume? What percentage of the total kcal in her diet was derived from each of the three nutrients? 600 CHO kcal from CHO 600 = 50% CHO 360 Fat total kcal 1200 240 Pro 1200 Total kcal kcal from Fat 360 = 30% Fat total kcal 1200 kcal from Pro 240 = 20% Pro total kcal 1200

1. If you consumed 400 kcal from CHO, 630 kcal from fat and 540 kcal from protein, what percentage of the total kcal was derived from each of the three energy providing nutrients?

2. A bran muffin contains 12 kcal from protein, 45 kcal from fat and 17 kcal from CHO. How many total kcal does the muffin provide? What percentage of the kcal in the muffin comes from each of the three macronutrients? If you know the number of grams of each nutrient in a food item, multiply the grams times how many calories per gram that nutrient provides.

3. A cup of chocolate ice cream contains 34 g fat, 50g CHO and 12 g protein. How many kcal are in the 1 cup portion? What is the percentage of calories from each nutrient?
