Answer:
Explanation:
A)
The formula for regression is,
ln(Cell Phone Subscribers) = -820.894 + 0.411704 Year
or,
Percentage of Cell Phone Subscribers = exp(-820.894 + 0.411704 Year)
For the year 2005,
Percentage of Cell Phone Subscribers = exp(-820.894 + 0.411704 * 2005)
= 96.79%
B)
The significance of the slope has a p-value close to 0 (0.000). Hence, the model holds statistical significance and its predictions are very reliable.
In the UK, it is estimated there are 22.36 million households, and collectively they pay approximately £2,938 million annually for electricity, assuming a 365-day year. Therefore, the total amount paid by UK households each year for electricity is £2,938 million.

= $7,750 - $2,750
= $5,000
3. For Bob’s value added
It corresponds to
= $20,000 - $7,750
= $12,250
This process applies equally to all three.
