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.

ASHA 777 [7]

Answer:

Cost of goods sold=$955000

Explanation:

we know that to calculate cost of goods sold we have to first finds cost of goods manufactured and to calculate cost of goods manufactured we will need total manufacturing cost.

Step#01: Total manufacturing cost=?

Total manufacturing cost= raw material used+direct labour+ factory overhead

Raw material used=?

     Raw material (open)=         72000

Add:  Raw material purchase=<u>467000</u>

                                                  539000

less: Raw material (ending)=   (<u>93000</u>)

      Raw material used            446000

Total manufacturing cost=446000+363000+213000=1021000

Step#2: Cost of goods manufactured (COGM)=?

we know that: COGM= Total manufacturing cost+ work in process (open)-work in process (end)

          COGM= 1021000+63000-84000=1000,000

Step#3: Cost of goods sold (COGS)=?

 we know that : COGS= Cost of goods manufactured+finished goods (open)-finished goods (ending)

               COGS= 1000000+171000-216000=955000

SVETLANKA909090 [29]

<em>MISSING INFORMATION:</em>

   concept                     //    Year 2     //     Year 1

Sales                                     7,620             7,450

Account Receivables             655                588

Answer:

Yes, there is. The days to collect increase by 4.16 to 29.77 from 26.61

Which is a bad sing as the company delays more to collect form their customers

Explanation:

Account Receivable turnover:

Average receivable:

(458 + 588 ) / 2  =  523

7,450 / 523 =   14.25

Days to collect: 365 / 14.25 = 25,61

Second Year:

Average receivable: (655 + 588) / 2 = 621.5

Turnover: 7,620 / 621.5 =  12.26

Days to collect: 365 / 12.26 = 29,77

29.77 - 25.61 = 4.16

Answer:

The question is incomplete. The complete question is given below:

              Selling Price per unit Variable  cost per unit

Product  

Trunk Switch             $60.00               $28.00

Gas door             $75.00                $33.00

Glove Box            $40.00              $22.00

Answer Trunk 240 units, Gas 240 units and Box 60 units

Explanation:

The break-even point is the activity level where the total revenue of a business  exactly equals its cost. At the break-even point, <em>the total profit made will be zero</em>. This analysis enables a firm to determine ahead the number of units to must be produced, customers that must served in order to cover its fixed costs.

Calculation

A break-even point can be calculated as follows:

For single-product scenario:  

Break-even point (in units)= Total general fixed cost for the period/                (selling price-variable cost )

Multiple-products scenario= Total general fixed cost for the period/Average contribution per unit

Total general fixed costs are period costs which remain unchanged within a given activity level and cannot be traced to be incurred for a particular product.

                                       Trunk           Gas              Box  

                                          $                 $                   $

Selling price                      60              75                   40

Variable cost                    (28)             (33)               (22)

Contribution per unit        32                42                  18

Cont. from a mix (sp×unit) 128              168                   18

Average cont. per mix = (128+168+18)/(4+4+1)= $34.89

Break-even point (in units)=  $18,840/$34.89

                                       = 540 units

Total units to be sold to break even is 540 units. This will be distributed across the three products using the sales mix as follows:

Trunk = 4/9× 540 units= 240 units

Gas = 4/9 × 540 = 240 units

Box = 1/9 *540 = 60 units

DATA

Fair value = 588,000

Cost = 542,000

Revaluation gain = Current fair value - Cost

Revaluation gain = 588,000 - 542,000

Revaluation gain = $46,000

The revaluation gain of $46,000 will be reported in other compreensive income of smith's financial statements.
