Answer:

D) Quantity sold rose while the effect on price is ambiguous.

Explanation:

Two separate things happened here;

  • Change in consumer habits have shifted the the demand curve to the right, increasing the quantity demanded at every price level.
  • Better technology and lower costs have also shifted the supply curve to the right, increasing the quantity supplied at every price level.

One thing is certain, the quantity demanded and supplied increased, so the total quantity sold definitely increased. The price issue is not certain because you would need additional information about which shift was larger, the shift of the supply curve or the demand curve.

An engineer bought a $1000 bond of an American airline for $875 just after an interest payment had been made. The bond paid a 6%
goldenfox [79]

Answer:

Number of coupon payments = 13.5*2= 27

Coupon = 6%*1000/2= 30

Let rate be r

Present value of all future payments = $87

875 = 30*(1-1/(1+r)^27)/r + 1000/(1+r)^27

R= 3.74%

Nominal rate = 3.74%*2 = 7.49%

A 30-year zero coupon bond with a face value of $5,000 is currently selling for $1,156.88 and has a market rate of interest of 5
daser333 [38]

Answer:

Price will increase by $277.58

Explanation:

Market rate of Interest of a zero coupon bond can be determined by following formula

Market Rate of Interest = [ ( F / P )^(1/30) ] - 1

4.25% = [ ( $5000 / P )^(1/30) ] - 1

0.0425 + 1 = ( $5000 / P )^1/30

( 1.0425 )^30 = (( $5000 / P )^1/30)^30

3.4856 = $5000 / P

P = $5,000 / 3.4856

P = $1,434.46

Now Calculate the change in Price

Change in price = $1,434.46 - $1,156.88 = $277.58

Price will increase by $277.58

Granite State Airlines serves the route between New York and Portsmouth, NH, with a single-flight-daily 100-seat aircraft. The o
TEA [102]

Answer:

Given data: One flight with total seats = 100

Full fare passengers, cost per ticket=$150, mean=56 passengers, SD=23

Discount fare passengers, cost per ticket=$100, mean=88 passengers, SD=44

(a) Here, though there is a hint to use the CDF, since the confidence interval is not given we will make some simplying assumptions that will reduce the complexity of the question, of course keeping the question statistically correct.

this question wants us to maximize total revenue per flight (one way), we can do that by taking only full fare passengers or total revenue will be 150*100=$15,000, but since historical probability shows a mean of 56 with a standard deviation of 23, we can assume in best case scenario total full fare ticket passengers will be 56+23=79, leaving 21 tickets for discount passenger, in this case the total revenues will be 79*150+21*100=$13,950

(b) Now, the new constrained policy is giving a clear cut number of seats to each category of pasengers, 44 for discount (total revenues 44*100) and 56 for full fare (total revenues 56*150) both of which are within the probabilities given earlier (full fare mean=56, discount mean=88). Total revenues in case will be 44*100+56*150=$12,800.

(c) Gain is the difference of the excess revenues in both cases of optimal total revenues and limited seats policy or answer (a) - answer (b) = $13,950- $12,800=$1,150

(d) Realistically speaking, there is no answer for this question without a clear cut confidence interval. Another simplifying assumption we can make here is taking the mean passengers as expected bookings (can be tweaked once confidence interval or degree of significance is given). so total revenues in this case will be 44*100 from discount and 56*150 from full fare passengers. That is still similar to answer (c) due to our assumption/lack of constraints, so our optimal booking will be 54 full fare tickets and 44 discount passenger tickets. You can also take worst case scenario by subtracting SD of each passenger type from the mean or go the best case scenario in which SD of full fare will be added to the mean while the pending seats (left over from 100) will be the total to discount fare for optimal revenue collection.

The mean cost of a meal for two in a mid-range restaurant in Tokyo is $40 (Numbeo website, December 14, 2014). How do prices for
natali 33 [55]

Answer:

a. 2.13. b. (30.53, 34.79). c. The mean prices for two in mid-range restaurants in Hong Kong are relatively less than those in Tokyo restaurants.

Explanation:

The size of the sample is 42 and the mean of the sample is ∑x_{i}n = 32.66 and the standard deviation of the sample (σ) is √[∑(x_{i}-μ)^2 - 1] = √46.6092 = 6.8271

a. α = 1 - (95/100) = 0.05; α/2 = 0.025; the degree of freedom = n-1 = 42-1 = 41; tα/2 = t0.025 = 2.02. Thus, the error margin = (tα/2)*(σ/√n) = 2.02*(6.83/√42) = 2.1279

b. Lower level limit = 32.66 - 2.1279 = 30.5321; Upper level limit = 32.66+2.1279 = 34.7879. The interval estimate = (mean± margin of error) = (30.53, 34.79).

c. The mean prices for two in mid-range restaurants in Hong Kong are relatively less than those in Tokyo restaurants.
