Like toys r us it failed because they always had low costs and low profits from their toys.
<span>Assume
that Jocelyn is comparing two fixed-rate loan options, a 15 year and a
30 year mortgage. Both options have the same interest rate and amount
borrowed. The 30 year, when compared to the 15 year loan will have a lower monthly payment and a higher total cost when
repayment is completed.
The longer the spread of an annuity payment the lower the monthly payment and the higher the total cost of the loan.

Answer:
c. a significant amount of market power
Explanation:
Cross price elasticity measures the responsiveness of quantity demanded of a good to the changes in price of another good.
If the cross price elascitiy is postive, the goods are subsituites.
If the cross price elasticity is negative, the goods are complementary goods.
If the cross price elasticitiy is low the firm has market power. It means that it's consumers do not change the quantity demanded when the price of the good changes
If the cross price elasticitiy is high, the market has low market power.
I hope my answer helps you.
a) ( 0.8509718, 0.8890282)
b) ( 0.7255, 0.7745)
Explanation:
(a)
Given that , a = 0.05, Z(0.025) =1.96 (from standard normal table)
So Margin of error = Z × sqrt(p × (1-p)/n) = 1.96 × sqrt(0.87 × (1-0.87) / 1200)
=0.01902816
So 95 % confidence interval is
p+/-E
0.87+/-0.01902816
( 0.8509718, 0.8890282)
(b)
Margin of error = 1.96 × sqrt (0.75 × (1-0.75) / 1200) = 0.0245
So 95% confidence interval is
p+/-E
0.75+/-0.0245
( 0.7255, 0.7745)
