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: C. it's a good time to buy the wood.
Explanation:
$500 = 738NZ dollars, therefore 738 NZ dollar ÷ $500 = 1.476NZ dollar
The current exchange rate is $1 = 1.476NZ dollar
10 foot slab costs $5000, Tee Golf Resort will pay $ 3387.53 ($5000/1.476NZ)
if they import wood from New Zealand. Tee Golf Resort will pay less than $5000 if they import Wood from New Zealand at the current exchange rate. This is a Good time for them to import woods
Answer:
False
Explanation:
Revenue tariff means increasing earnings. It will raise government revenue instead of protecting domestic ventures. It is a direct income in the form of tax to obtain from corporate revenues.
On the other hand, protective tariffs are designed to protect domestic producers. It protects local manufacturers by imposing a heavy duty on imported products, which enables the products to become less attractive. Therefore, the aim is to reduce imports.
Answer:
$ 2,829,276
Explanation:
The budgeted direct labour cost is going to be based on the budgeted production units.
Production budget = sales budget + closing inventory -opening inventory
Production budget = 46,000 - 140 + 580 = 45,560
Labour budget = Production budget× hours per unit
= 45,560× 2.7 hrs × $23
= $ 2,829,276
