Answer:

P-value is greater than the significance level, we fail to reject null hypothesis.

Explanation:

Here,  

Sample size = n = 120

Sample proportion = p = 0.6500

Population Proportion = P_{0} = 0.5

Level of significance = α = 0.02

<u />

<u>Step 1: </u>

H_{0}: p = 0.5

H_{1}: p < 0.5 (Left tailed test)

<u></u>

<u>Step 2: </u>

The critical vale is = 2.0537

<u></u>

<u>Step 3:  </u>

The test statistic is,

z =  \frac{p - p_{0} }{\sqrt{\frac{p_{0} (1-p_{0}) }{n} } }

<u>Step 5: </u>

Conclusion using critical value: Since the test statistic value is greater than the critical value, we fail to reject null hypothesis.

<u>Step 6:  </u>

Conclusion using P-value: Since the P-value is greater than the significance level, we fail to reject the null hypothesis.

Airlines can price discriminate by determining people's _______ to pay for luggage accommodations. Some customers will check a b
mr Goodwill [35]

Answer:

Willingness to pay

Revenue

Two

Elastic

Inelastic

Explanation:

Price discrimination is when a producer or a seller charges different prices for the same product usually in different markets.

In price discrimination, a seller attempts to remove or reduce consumer surplus by charging the consumer at his willingness to pay. For price discrimination to be effective, a seller must be able to estimate the willingness to pay of consumers.

Price discrimination is successful when a seller earns higher profits when she discriminates compared to when she didn't price discriminate.

Price discrimination exists in the airline industry. One of the ways price discrimination exists in the airline industry is through charging to check bags. Customers ( people who board airplanes) are distributed into two groups- those who won't pay to check bags and those who would pay to check bags.

It is assumed that those who would pay to check their bags have a price inelastic demand because they are indifferent to paying an extra amount for their luggage.

Inelastic demand is defined as when a small change in price has no effect on quantity demanded.

While it is assumed that those who won't pay to check their bags have an elastic demand because they are unwilling to pay extra to check their luggages.

Elastic demand is when a change in price has effect on quantity demanded.

When originally purchased, a truck costing BD 23.000 had an estimated useful life of 8 years and an estimated salvage value of B
GREYUIT [131]

Answer:

d. BD 2,500

Explanation:

Accumulated Depreciation through the end of year 4 = [ Asset's cost - Salvage Value) / Estimated Useful Life] * Years Elapsed

= [(23,000 - 3,000)/8] * 4

= BD 10,000

Depreciation in Year 3 = [Asset's cost - Salvage Value - Accumulated Depreciation] / Remaining Estimated Useful Life

Depreciation in Year 3 = [23,000 - 3,000 - 10,000] / 4

Depreciation in Year 3 = 10,000 / 4

Depreciation in Year 3 = BD 2,500

A benchmark market value index is comprised of three stocks. yesterday the three stocks were priced at $12, $20, and $60. the nu
Olenka [21]

Answer: The one day rate of return on the stock is 1.49%

We arrive at the answer in the following manner:

First we need to calculate yesterday's and today's index values.

For that we need to find weights of each day based on market capitalization.

Market Capitalization _{ a stock} = Market Price * No .of outstanding shares

The weight of a company in the index is calculated by dividing the market capitalization  of a company by the total market capitalization of all the companies whose shares are a part of the index.

Weight_{Company A} =\frac{Mkt Cap of company A}{Total Market cap}

Then, we multiply the share price of each company with their respective weights and find the total to arrive at the index value for one day.

<u>Yesterday's Index Value</u>

Stock        Price         No. of shares      Mkt Cap  Weight  Weight*Price

A               12               600000        7200000      0.25      2.96 (0.25*12)    

B               20               500000       10000000    0.34      6.85(0.34*20)

C               60               200000       <u>12000000</u>     <u>0.41</u>      <u>24.66  </u>(0.41*60)

Total                                                 29200000     1.00      34.47

We calculate the weight for stock A as follows:

Weight_{A} =\frac{72,00,000}{2,92,00,000} = 0.2466 = 0.25

We calculate the weights of the remaining stocks in a similar manner.

Please note that the sum total of all weights must add up to 1.

The sum total of the last column (Price * Weight) is yesterday's index value.

We repeat the same steps with today's market price to arrive at today's index value.

<u>Today's index Value</u>

Stock        Price   No. of shares       Mkt Cap     Weight    Weight*Price

A               16               600000       96,00,000     0.31        4.95 (0.31*16)    

B               18               500000       90,00,000     0.29       5.23  (0.29*18)

C               62               200000    <u>1,24,00,000</u>     <u>0.40</u>     <u>24.80</u>(0.40*62)

Total                                                3,10,00,000     1.00     34.98

<u>One-day Rate of Return</u>

We can calculate the one day rate of return on the index as follows:

Rate of return = [\frac{(Today's index value - Yesterday's index value}{Yesterday's index value}) * 100

Rate of Return = ( \frac{34.98 - 34.47}{34.47}) * 100

Rate of return = (\frac{0.51}{34.47}) *100

Rate of return = 0.01494 or 1.49%
