Answer:

Andy's proposal is more likely than Brad's to suffer from bias due to issues with "representativeness."

The above statement is True.

Explanation:

AB testing compares the click-through rate of the two agencies only. This test runs on random basis. It is a straightforward exercise that affects the business in the short-run and its effect are temporary. While difference-in-difference testing studies the non-randomized data. The rates are higher but it covers the whole data.  

Andy's proposal is more likely than Brad's to suffer from bias to issues with 'representatives'. Andy opts for A/B testing while Brad opts for difference-in-difference testing. Therefore, Andy's proposal is more likely to bias due to limited verification.  

Hence, the given statement is  

'True'

UPS, a delivery services company, has a beta of 1.4, and Wal-Mart has a beta of 0.9. The risk-free rate of interest is 4% and th
Elena-2011 [213]

Answer:

10.9%

Explanation:

to calculate the expected return of the portfolio, we first need to calculate the portfolio's beta:

the portfolio beta = (beta UPS stock x weight UPS stock) + (beta Walmart stock x weight Walmart) = (1.4 x 50%) + (0.9 x 50%) = 0.7 + 0.45 = 1.15

portfolio's expected return = risk free rate + (portfolio beta x market risk premium) = 4% + (1.15 x 6%) = 4% + 6.9% = 10.9%

You and a rival are engaged in a game in which there are three possible outcomes: you win, your rival wins (you lose), or the tw
kherson [118]

Answer:

A) There is a 50% chance the game ends in a tie, 10% chance you win (and therefore a 40%  chance you lose).

expected value = (50% x 20) + (10% x 50) + (40% x 0) = 10 + 5 + 0 = 15

B) There is a 50-50 chance of winning and there are no ties.

expected value = (50% x 50) + (50% x 0) + = 25 + 0 = 25

C) There is an 80% chance you lose and a 10% chance you win or tie.

expected value = (10% x 20) + (10% x 50) + (80% x 0) = 2 + 5 + 0 = 7

The expected value of an event is determined by adding up all the possible outcomes multiplied by their respective value.

Endor Company begins the year with $110,000 of goods in inventory. At year-end, the amount in inventory has increased to $118,00
Arada [10]

Answer:

11.40

32 days

Explanation:

Inventory turnover and days of sales of inventory are examples of activity ratios.

They are used to measure the efficiency of performing daily tasks

inventory turnover =  Cost of goods sold/ average inventory

Average inventory = ($118,000 + $110,000) / 2 = $114,000

Inventory turnover =  $1,300,000 / $114,000 = 11.40

days of sales of inventory = 365 / inventory turnover = 365 / 11.40 = 32 days

ella [17]

Answer:

b. $433,750

Explanation:

The ending balance in retained earnings can be calculated as;

= Beginning balance + Net income - Cash dividends

Given that;

Beginning balance = $430,000

Net income = $60,000

Cash dividends = $56,250

= $430,000 + $60,000 - $56,250

= $433,750

Therefore, the ending balance in retained earnings is $433,750
