An economist conducted a study of the possible association between weekly income and weekly grocery expenditures. The particular

interest was whether higher income would result in shoppers spending more on groceries. A random sample of shoppers at a local supermarket was obtained, and a questionnaire was administered asking about the weekly income of the shopper’s family and the grocery bill for that week. The gender of the shopper was also obtained. The least squares line had a slope of 0.079 . The average amount by which the grocery bill increases for an increase of $100 per week is given by:a. $7.9 .b. The answer cannot be determined from the information provided.c. $0.079 .d. $10.0 .

The answer cannot be determined from the information provided.

Answer: Option B.

<u>Explanation:</u>

A linear regression line has an equation in the form Y = a + bX, where X stands for the explanatory variable and Y is used to denote the dependent variable in the equation. The slope of the line is b, and a is the intercept (the value of y when x = 0).

A regression line (LSRL - Least Squares Regression Line) is a straight line that explains how a dependent variable y changes as an explanatory variable x changes. The line is a mathematical model used to predict the value of y for a given x. Regression requires that we have an explanatory and response variable.

What were the economic changes that revolutionized manufacturing in the eighteenth century and led to the factory system?
Daniel [21]

Answer:

The industrial revolution affected the whole global economy, social relations, and culture.

The industrial revolution changed how goods were manufactured, and it all started with the European accumulation of capital and the invention of the steam engine.

The two major sources of energy were coal and oil that were used to power steam engines that moved machinery using water steam. That led to work specialization and urbanization (people moving into large urban areas).

The industrial revolution first started in northwestern Europe, but it then spread to the US, Russia and Japan. The global economy developed new patterns of global trade and production between nations that produced resources and those that processed them and produced goods.

Exporting economies grew around the world because of the need for exporting both raw materials and food supplies from resource producing nations, and the need for exporting finished goods form industrialized nations.

Olin [163]

Answer:

$7,899,827

Explanation:

The computation of the maximum increase in money supply is shown below:

Data given in the question

Additional value in excess reserves = $868,981

Reserve ratio = 11%

By considering the above information, the maximum increase in money supply is

= Additional value in excess reserves × 100 ÷ reserve ratio

= $868,981 × 100 ÷ 11

= $868,981 × 9.09

= $7,899,827

You find the following corporate bond quotes. To calculate the number of years until maturity, assume that it is currently Janua
Oduvanchick [21]

Answer:

the yield to maturity for the bond issued by Xenon, Inc = 6.92%

Explanation:

<em>IMPORTANT NOTE: The data of the calculation was obtained from an online book.</em>

<em />

Yield to Maturity [YTM] of the Bond

Yield to Maturity [YTM] = Coupon Amount + [(Par Value – Bond Price) / Maturity Years] / [(Par Value + Bond Price)/2]

Par Value = $2,000

Coupon Amount = $126 [$2,000 x 6.30%]

Bond Price = $1,885.82 [$2,000 x 94.291%]

Maturity Years = 15 Years [Jan 15,2016 to Jan 15,2031]

Therefore, Yield to Maturity [YTM] = Coupon Amount + [(Par Value – Bond Price) / Maturity Years] / [(Par Value + Bond Price)/2]

= [$126 + {($2,000 – $1,885.82) / 15 Years)] / [($2,000 + $1,885.82) / 2}]

= [($126 + $7.61) / $ 1,942.91]

= 0.0692

= 6.92%

<h2> </h2><h2>Therefore, the yield to maturity for the bond issued by Xenon, Inc = 6.92%</h2>

The management of Bullinger Corporation would like to investigate the possibility of basing its predetermined overhead rate on a
Anit [1.1K]

Answer:

$5,160

Explanation:

Predetermined Overhead Rate on Capacity = Total Estimated Manufacturing Overhead / Estimated Capacity for the Year

Predetermined Overhead Rate on Capacity = $34,840 / 29,000 MH

Predetermined Overhead Rate on Capacity = $1.20 MH

Actual use of capacity = 24,700 hours

Unused hours = 29,000 hours - 24,700 hours

Unused hours = 4,300 hour

Cost of unused capacity = 4,300 hours * $1.20 MH

Cost of unused capacity = $5,160
