Explanation:
To find the income elasticity we first must recall the formula
which is the percentage change in quantity when income increases in one percent.
From the demand curve we can find by taking derivative of Q with respect to Y:
Next we need to know what is the income at the equilibrium quantity of 1300, which we can back out from the data given in the question
Then
The sample size needed to obtaing a 95% confidence interval that is within 8 percentage points of the true proportion is given by:
where: p is a previously known proportion about the population,
is the 95% z-statistics, B is the bound of error = 8.
Because, we have no prior knowledge about the true proportion of the population, we use 50%.
Thus,
Therefore, the number of <span>randomly selected sales transactions that must be surveyed to determine the percentage that transpired over the internet </span><span><span>within eight percentage points of the true population percentage for all sales transactions</span> with a 95% confident</span> is 151.

Answer:
$ 127,773.36
Explanation:
The professor will be in sabbatical in years 7, 14, 21, 28, 35 and 42
In each of these years, he receives full pay amounting to=50,000
The PV of the sabbatical full pay
=
=50,000/(1+4%)^7+ 50,000/(1+4%)^14+ 50,000/(1+4%)^21+ 50,000/(1+4%)^28+50,000
/(1+4%)^35+ 50,000/(1+4%)^42
==50,000/(1+4%)^7+ 50,000/(1+4%)^14+ 50,000/(1+4%)^21+ 50,000/(1+4%)^28+50,000
/(1+4%)^35+ 50,000/(1+4%)^42
=
=37,993.92 + 28,868.36 + 21,939.45 + 16,672.22 + 12,671.06 + 9,628.35
= $ 127,773.36
Thus, at an interest rate of 4%, the present value of all the sabbatical earnings amount to $ 127,773.36
