another. Two analysts, Andy and Brad, are asked to test the effectiveness of the two agencies. Andy proposes an A/B test that compares the click-through rates per ad of the two agencies. Brad proposes a difference-in-difference test in which the budgets for both agencies are increased by 50%, and the percentage changes in the click-through rates are compared. What might be the sources of selection bias for the two proposals? Which is likely to be smaller?

Answer:

Issues with "representatives"; Andy.

Explanation:

So, from the question we can see that; '' est the effectiveness of the two agencies. Andy proposes an A/B test that compares the click-through rates per ad of the two agencies. Brad proposes a difference-in-difference test in which the budgets for both agencies are increased by 50%, and the percentage changes in the click-through rates are compared."

Andy proposes an A/B test is based on randomized data and what A/B test does is to compare the click through rates of the two agencies.

Brad proposes a difference-in-difference test is based on data that are not treated randomly.

The proposal that is more likely to be biased is that of the proposal by Andy and this can be attributed to the issue known as the "representatives" that is to say to say that there are limited verification which will make Andy's proposal to be biased.

Identify how to calculate nominal interest rates and real interest rates. Assume that you put $100 in the bank. Use numeric exam
Alik [6]

Answer: Please refer to Explanation

Explanation:

To answer this question we will assume that the Nominal Interest rate is equal to 10% then we can be free to manipulate the Real Interest Rate.

Now the Real Interest Rate is the Nominal Interest Rate adjusted for inflation in the following manner,

Real interest rate= Nominal interest rate - inflation rate.

Let's go through 3 scenarios now.

1. REAL interest rate is positive.

If the Real Interest rate is positive, that would mean that Inflation rate is LESS than the Nominal Interest rate.

Assuming the inflation rate is 5% then that would mean that real interest rate is,

= 10% - 5%

= 5%.

Seeing as you have $100 in the bank. If using Nominal Rates alone you would have earned,

= 100 * (1+0.1)

= $110

However with a rate that caters for inflation (Real Interest Rate) you would earn only,

= 100 * (1 + 0.05)

= $105

2. REAL interest rate stays the same

If the Real Interest rate does not change, that would mean that Inflation rate is EQUAL to Nominal Interest rate.

Assuming the inflation rate is 10% then that would mean that real interest rate is,

= 10% - 10%

= 0% meaning that there was no change.

You have that same $100 in the bank. If using Nominal Rates alone you would have earned,

= 100 * (1+0.1)

= $110

However with a rate that caters for inflation (Real Interest Rate) you would earn only,

= 100 * (1 + 0.00)

= $100

Your money in the bank would in REAL TERMS not have changed because whatever profit you made was wiped out by inflation.

3. REAL interest rate is negative.

If the Real Interest rate is negative, that would sadly mean that Inflation rate is MORE than the Nominal Interest rate.

Assuming the inflation rate is 15% then that would mean that real interest rate is,

= 10% - 15%

= -5%.

Seeing as you have $100 in the bank. If using Nominal Rates alone you would have earned,

= 100 * (1+0.1)

= $110

However with a rate that caters for inflation (Real Interest Rate) you would earn only,

= 100 * (1 - 0.05)

= $95

If inflation were to be catered for, the value of your money has actually decreased from $100 to $95 because inflation rose at a faster rate than nominal inflation. This means that the money you had can buy only 95% of what it could before.

This is why the Real Interest Rate is Important. It shows you whether you are actually making a profit based on the rate at which prices are rising in the Economy. It is crucial that the Real Rate is calculated so that you get adequate compensation for your Investment.

What is the balance between supply and demand called ?
n200080 [17]

The balance between supply and demand is known as the market equilibrium.

The supply and demand are determined through the price mechanism in a free market. Such as if the goods or services are bought more frequently then their prices will go up and vice versa.

This means that the price mechanism helps to determine what goods are to be produced. In the case where the demand for good increase will result in price go up and will ultimately result in producers supplying more of those goods.

This system of price helps to scale the point where competing demands may be weighed by the consumer or producer requirements.

However, the movement towards the price equilibrium and the resulting balance between the supply and demand is known as the market equilibrium.

Tim Urban, owner/manager of Urban's Motor Court in Key West, is considering outsourcing the daily room cleanup for his motel to
nlexa [21]

Answer:

Based on the given information related to costs for each of the options, the crossover point for Tim = <u>6,000</u> room nights (round your response to the nearest whole number). If the number of room nights is less than the crossover point, then <u>OUTSOURCING (Duffy's Maid Service)</u> is the best option available to Tim. Based on the given room nights that Tim expects to rent (18, 250), the best option is to keep doing the service <u>INSOURCING (doing it himself)</u>.

Explanation:

Currently, before outsourcing, Tim's total cost = $228,125 + $61,000 = $289,125. On average, he spends $15.84247 per room.

The Duffy's Maid Service offer would represent a total cost of $337,625 + $25,000 = $362,625 for the same occupation level.

the crossover point for Tim:

12.5x + 61,000 = 18.5x + 25,000

36,000 = 6x

x = 6,000 room nights

(6,000 x 12.50) + 61,000 = (6,000 x 18.50) + 25,000 = $136,000
