A recent report indicated that families in a certain country typically spend about $175 per week on groceries. To investigate wh

ether families in a certain city typically spend more than $175 per week, an economist selected a random sample of 500 families in the city and found the sample mean to be $176.24. With all conditions for inference met, a hypothesis test resulted in a pp-value of 0.0021.
At the significance level of α=0.05α=0.05, which of the following is a correct conclusion?
A. The pp-value is less than 0.05, and the null hypothesis is rejected. There is convincing statistical evidence that the mean is greater than $175.
The pp-value is less than 0.05, and the null hypothesis is not rejected. There is convincing statistical evidence that the mean is greater than $175.
B. The pp-value is less than 0.05, and the null hypothesis is not rejected. There is not convincing statistical evidence that the mean is greater than $175.
C. The pp-value is greater than 0.05, and the null hypothesis is rejected. There is convincing statistical evidence that the mean is greater than $175.
D. The pp-value is greater than 0.05, and the null hypothesis is not rejected. There is not convincing statistical evidence that the mean is greater than $175.

Answer:

Option B

Explanation:

Null hypothesis: ∪ = $175

Alternative hypothesis: ∪ₐ ≠ $175

With a pp value of 0.0021 which is less than value at the level of significance, the null hypothesis is not rejected as there is no sufficient statistical evidence that the mean is greater than $175.

Rasmussen Corporation expects to incur indirect overhead costs of $80,000 per month and direct manufacturing costs of $12 per unit. The expected production activity for the first four months of 2017 is as follows: January February March April Estimated production in units 6,000 7,000 3,000 4,000

Estimated manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base

January:

Estimated manufacturing overhead rate= (80,000/6,000)+12= 25.33 per unit

February:

Estimated manufacturing overhead rate= $23.43

March:

Estimated manufacturing overhead rate= 38.67

April:

Estimated manufacturing overhead rate= $32

Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base

January= 6,000*25.33= $151,980

February= 7,000*23.43= $164,010

March= 3,000*38.67= 116,010

April= 4,000*32= $128,000

Consider two neighboring island countries called Felicidad and Bellissima. They each have 4 million labor hours available per mo
Ilia_Sergeevich [38]

Answer:

Bellisima's opportunity cost:  

  • Production of corn per million hours of labor = 12 / 24 = 0.5 pairs of jeans of corn
  • Production of jeans per million hours of labor = 24 / 12 = 2 bushels of corn

Felicidad's opportunity cost:  

  • Production of corn per million hours of labor = 8 / 32 = 0.25 pairs of jeans of corn
  • Production of jeans per million hours of labor = 32 / 8 = 4 bushels of corn

Felicidad has a comparative advantage int he production of corn while Bellisima has a comparative advantage in the production of jeans.

If both countries specialize:

  • Felicidad will produce 128 million bushels of corn.
  • Bellisima will produce 48 million pairs of jeans.

Total production of corn has increased by 24 million bushels.

Total production of jeans has increased by 12 million pairs.

Assuming that Bellisima trades 26 million pairs of jeans and Felicidad exchanges 78 million bushels of corn, then:

  • Felicidad's consumption of jeans will increase by 2 million pairs, while their consumption of corn will increase by 50 million bushels.
  • Bellisima's consumption of jeans will increase by 10 million pairs, while their consumption of corn will increase by 6 million bushels.
