An urban economist wishes to estimate the mean amount of time people spend travelling to work. He obtains a random sample of 60

individuals who are in the labour force and finds that the mean travel time is 30.5 minutes. Assuming that the population standard deviation of travel time is 20.5 minutes, construct and interpret a 90% confidence interval for the mean travel time to work. (Note: the standard deviation is large, because some people work at home and thus travel 0 minutes and some people take transit which results in large travel times).

Answer:

An urban economist wishes to estimate the mean amount of time people spend traveling to work. He obtains a random sample of 50 individuals who are in the labor force and finds that the mean travel time is 24.2 minutes. Assuming the population standard deviation of travel time is 18.5 minutes, construct and interpret a 95% confidence interval for the mean travel time to work. Note: The standard deviation is large because many people work at home (travel time =0 minutes) and many have commutes in excess of 1 hour. (Source: Based on data obtained from the American Community Survey.)

Sag manufacturing is planning to sell 400,000 hammers for $6 per unit. The contribution margin ratio is 20%
Tasya [4]

The question is incomplete. The following is the complete question.

Sag Manufacturing is planning to sell 400,000 hammers for $6 per unit. The  contribution margin ratio is 20%. If Sweet will break even at this level of sales, what are  the fixed costs?

Answer:

Fixed costs are $480000

Explanation:

The break even sales is the value of total sales or total revenue where it equals total cost and the company makes no profit or no loss. The break even in sales is calculated by dividing the fixed costs by the contribution margin ratio.

Break even in sales = Fixed cost / Contribution margin ratio

Plugging in the available values we can calculate the value of fixed cost. We know that the break even in units is at 400000 units. Thus, its value in sale will be 400000 * 6 = 2400000

2400000 = Fixed cost / 0.2

2400000 * 0.2 = Fixed cost

Fixed costs = $480000

Mazyrski [523]

Answer:

Crane Company

1. Weighted average cost per unit = $25.032

2.                                       (1) LIFO         (2) FIFO          (3) Average-cost

Ending inventory                $1,580          $1,940                  $1,752

Cost of goods sold               6,180           5,820                   6,008

Sales revenue                    $9,150         $9,150                  $9,150

Gross profit                          2,970           3,330                    3,142

Gross profit rate                  32.5%          36.4%                   34.3%

Explanation:

a) Data and Calculations:

Date       Description              Units    Unit Cost or Selling Price         Total

Oct. 1      Beginning inventory  50            $22                           $1,100

Oct. 9     Purchase                   110              24                            2,640

Oct. 11    Sale                           (90)                                   $35               $3,150

Oct. 17    Purchase                   90              26                            2,340

Oct. 22  Sale                           (50)                                     40                2,000

Oct. 25  Purchase                   60              28                             1,680

Oct. 29  Sale                         (100)                                     40                4,000

Total                     310 (240) = 70                                             $7,760 $9,150

Weighted average cost per unit = $25.032

LIFO:

Ending inventory

= (50 * $22) + (20 * $24)

= $1,100 + $480

= $1,580

Cost of goods sold = $7,760 - $1,580 = $6,180

FIFO:l

Ending inventory:

= (60 * $28)  + (10 * $26)                  

= $1,680 + $260 = $1,940

Cost of goods sold = $7,760 - $1,940 = $5,820

Weighted-average costs:

Ending inventory = 70 * $25.032 = $1,752

Cost of goods sold = $7,760 = $1,752 = $6,008

Natali5045456 [20]

Answer:

Net Investment = 4,000

Explanation:

Gross Investment = 10,000

Depreciation = Market Value - Book value

Depreciation =26,000 - 20,000

Depreciation = 6,000

Net Investment = Gross Investment - Depreciation

Net Investment = 10,000 - 6,000

Net Investment = 4,000

NOTE: Gross investment for 2017 will be the 3 new beds that Sophie bought during 2017 at a total cost of 10,000. To calculate Net investment we should calculate depreciation first by deducting book value from market value.
