Answer:
The answer is below.
Explanation:
The z score is a used in statistics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
![z=\frac{x-\mu}{\sigma}\\\\where\ x=raw\ score, \mu=mean,\sigma=standard\ deviation\\\\For\ a\ sample\ size(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D%5C%5C%5C%5Cwhere%5C%20x%3Draw%5C%20score%2C%20%5Cmu%3Dmean%2C%5Csigma%3Dstandard%5C%20deviation%5C%5C%5C%5CFor%5C%20a%5C%20sample%5C%20size%28n%29%3A%5C%5C%5C%5Cz%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%2F%5Csqrt%7Bn%7D%20%7D)
a) Given that n = 100, μ = 2000, σ = 18
For x < 1995 millimeters:
![z=\frac{x-\mu}{\sigma/\sqrt{n} }=\frac{1995-2000}{18/\sqrt{100} } =-2.78](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%2F%5Csqrt%7Bn%7D%20%7D%3D%5Cfrac%7B1995-2000%7D%7B18%2F%5Csqrt%7B100%7D%20%7D%20%20%3D-2.78)
From the normal distribution table, P(x < 1995) = P(z < -2.78) = 0.0027
b) P(z > z*) = 10% = 0.1
P(z < z*) = 1 - 0.1 = 0.9
z* = 1.28
![z*=\frac{x-\mu}{\sigma/\sqrt{n} }\\\\1.28=\frac{x-2000}{18/\sqrt{100} }\\\\x-2000 =-2.304\\\\x=2002.3\ ml\\\\](https://tex.z-dn.net/?f=z%2A%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%2F%5Csqrt%7Bn%7D%20%7D%5C%5C%5C%5C1.28%3D%5Cfrac%7Bx-2000%7D%7B18%2F%5Csqrt%7B100%7D%20%7D%5C%5C%5C%5Cx-2000%20%20%3D-2.304%5C%5C%5C%5Cx%3D2002.3%5C%20ml%5C%5C%5C%5C)
From the normal distribution table, P(z < z
Answer:
a debit to Accounts Payable for $1,400 and a $1,400 credit to Purchase Returns allowances
Explanation:
Periodic inventory system is one that updates information on inventory on a periodic basis. This is opposite of perpetual inventory system that requires update of inventory system at all times.
In the scenario the merchandiser bought the goods on account. That means he did not pay cash but rather bought on credit.
On purchasing the items accounts payable will be credited thereby increasing the account balance.
Since the items are being returned a debit will be applied to accounts payable resulting in a decrease in the account balance.
A credit will now be posted to purchase returns allowances to show that products have been returned by a buyer
Answer:
$66,000
$304,000
Explanation:
The computation is shown below:
Total implicit cost is
= Job left cost + forgone the return on investment
= $60,000 + $100,000 × 6%
= $60,000 + $6,000
= $66,000
And, the total cost is
= explicit cost + implicit cost
= $50,000 + $180,000 + $8,000 + $66,000
= $304,000
We simply applied the above formulas so that the correct values could come
Answer:
what rate is he earning interest
Interest rate is 8%
Explanation:
I = C·i·t,
C Initial Investement
i Anul interest rate
t time
16000=20000*i*10
16000=200000*I
I=16000/200000
I=0,08
I=8%
Answer:
Real property consists of the land, land rights, and anything permanently attached to the land, while real estate consists of a structure attached to the land
