Answer:

Explanation:

A)

The regression equation is,

ln(Cell Phone Subscribers) = -820.894 + 0.411704 Year

or,

Percent of Cell Phone Subscribers = exp(--820.894 + 0.411704 Year)

For the year 2005,

Percent of Cell Phone Subscribers = exp(--820.894 + 0.411704 * 2005)

= 96.79%

B)

P-value for the significance of the slope is very low (0.000). Thus, the model is statistically significant and the prediction of the model is highly reliable.

Explanation:

Due to the rise of the India's pharmaceutical industry the US pharmaceutical companies benefit by the increase in volume of sales due to the low costs of imports.

The U.S. consumers benefited from rise in Indian pharmaceutical industries, because of lower cost medications, insurance, copays as well as out of pocket expenses and greater financial flexibility that offers pharmaceuticals developed at lower research and development (R&D) cost.

The U.S. pharmaceutical companies have major benefits from India because the people from India see others inputs instead of the goals for themselves and America is seen as an individualistic culture and there is lower power distance in America due to the fact that everyone is created equal which is why within America, people often to seek their own personal goals instead of the good of others.

Furthermore America is more concerned about self while India seeks to help the world globally which is why two different counties have to adapt to policies and procedures to respect exporting trade rights and this policy is known as the World Trade Organization.

Tanya [424]

Answer:

see below

Explanation:

Common stock = Assets - Liabilities - Retained earnings

Assets next year = $225,232 + $55,000 = $280,232

Liabilities remain unchanged

Retained earnings = Opening retained earnings + Net income - Dividends

= $36,493 + $44,200 - $12,000

= $68,693

Common stock next year

= $280,232 - $136,748 - $68,693

= $74,791
