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.

wlad13 [49]

Answer:

value of ending inventory under variable production is $104375

Explanation:

given data

Variable production costs = $12.50 per unit

variable selling and administrative expenses = $3.50 per unit

Fixed manufacturing overhead totals = $41,000

Fixed selling and administration expenses total = $45,000

production = 4,500 units

sales = 3,850 units

to find out

the dollar value of the ending inventory under variable costing would be

solution

we find here ending inventory that is express as

ending inventory = production - sale

ending inventory = 4500 - 3850

ending inventory = 8350

so

variable production cost of 8350 units are

variable production cost = 8350 × $12.50

variable production cost = $104375

so value of ending inventory under variable production is $104375

Anarel [89]

Answer:

The intrinsic value of A -$44.57 is higher than that of B- $ 29.71

<em>The intrinsic value is the present value of he expected future dividend discounted at he required rate of return.</em>

<em>So, we would work out the intrinsic value of the two stocks using the the formula below:</em>

Intrinsic value  = D× (1+r)/(k-g)

Intrinsic value of stock A

D-3, r-11%, g-4%

= 3 ×(1.04)/(0.11-0.04)

=$44.57

Intrinsic value of stock B

D-2, r-11%, g-4%

= 2 ×(1.04)/(0.11-0.04)

= $29.71
