From the given description, Chip is using an experimental design called (A) matching.

Matching <u>is a type of experimental design where the researcher divide his or her samples into two groups of treatment conditions, which serves to ensure that before the treatment, both groups have the samples with the same characteristics, thus ensuring that the results of the experiment would not be influenced by any confounding variables that the samples have.</u>

Chip is doing this to ensure that samples that have been influenced by other variables which determine their decision to hire are distributed evenly in both the experimental and control group.

RideAnS [48]

Answer:

increase by 400 billion dollars

Explanation:

marginal propensity to consume = mpc

tax multiplier = -mpc/1-mpc

from our question we were given mpc to be 0.8

-0.8/1-0.8

= -0.8/0.2

= -4

change in output = -4(-100)

= 400 billion dollars

for a $100 tax decrease, output will increase by $100 billion x 4

= $400 billion

Audio engineers at 3XT2 have determined that an anechoic additive will increase isolation and improve signal to noise by about 2
Crazy boy [7]

Answer:

The correct answer is $83230

Explanation:

Solution

Given that:

The Present worth of geometric series is shown below

= A *[1 - (1+g)^n /(1+i)^n] / (i-g)

Now,

The present  cost of worth from EOY 5 to EOY 13 at EOY 4 = 7000 *[1 - (1+0.12)^9 /(1+0.15)^9] / (0.15-0.12)

Thus,

= 7000 *[1 - (1.12)^9 /(1.15)^9] / (0.03)

Which is,

= 7000 * 7.0572647

= 49400.85

Now, The NPW of all costs = 35000 + 7000*(P/A,15%,4) + 49400.85*(P/F,15%,4)

= 35000 + 7000*2.854978 + 49400.85*0.571753

= 83229.93

Therefore the sound improvement better result in a net present worth profit of how much to negate the costs is $83229.93 or 83230

Note: EOY = End of year.
