Explanation:

The complete question statement is given;

The time to replace vehicle wiper blades at a service center was monitored using a mean and a range chart. six samples of n = 20 observations have been obtained and the sample means and ranges computed:

Sample Mean Range Sample Mean Range

1 3.06 .42

2 3.15 .50

3 3.11 .41

4 3.13 .46

5 3.06 .46

6 3.09 .45

Determine the upper limits for the mean

Determine the lower control limit for the mean

Solution

To determine, the upper limit and the lower limit, we need to first find the average of the mean for six sample

Mean average = 3.1

Range average = 0.45

Now for the upper limit; the formula is

= Mean Average + 0.18 (Range average)

= 3.1 + 0.18 (0.45)

=3.181

Now for the lower limit; the formula is

= Mean Average - 0.18 (Range average)

= 3.1 - 0.18 (0.45)

=3.01

Answer:

control limits for X (mean time) = 3.1 +/- 0.081 or (3.181 ; 3.019)

control limits for R (range) = (0.1845 ; 0.711)

Explanation:

Sample              Mean             Range

1                         3.06                 0.42

2                        3.15                  0.50

3                        3.11                   0.41

4                        3.13                  0.46

5                        3.06                 0.46

6                        3.09                 0.45

average             3.10                 0.45

to determine the upper and lower limits we need to find z in table for R charts, and look at the 20th value for A₂, D₃ and D₄:

  • z for A₂ (n = 20) = 0.18
  • z for D₃ (n = 20) = 0.41
  • z for D₄ (n = 20) = 1.59

control limits for X = average mean +/- z(A₂) x average range

control limits for X = 3.1 +/- (0.18 x 0.45)

control limits for X = 3.1 +/- 0.081 or (3.181 ; 3.019)

now the control limits for R (range):

lower control limit = D₃ x average range = 0.41 x 0.45 = 0.1845

upper control limit = D₄ x average range = 1.59 x 0.45 = 0.711

control limits for R (range) = (0.1845 ; 0.711)

                                               Company        East         Central         West

Sales                                    $ 1,500,000  $350,000  $620,000  $530,000

Variable expenses                   655,500     154,000      241,800    259,700

Contribution margin                 844,500  $196,000   $378,200  $270,300

Traceable fixed expenses        819,000    294,000    329,000     196,000

Non-traceable fixed expenses 110,000

Net operating income (loss) $ (84,500)  $(98,000)    $49,200    $74,300

2. Decrease in net operating loss = $45,200

Explanation:

a) Data and Calculations:

Wingate's most recent monthly contribution format income statement:

Sales                                    $ 1,500,000

Variable expenses                   655,500

Contribution margin                 844,500

Fixed expenses                       929,000

Net operating income (loss) $ (84,500)

Additional data:

Division                                       East        Central         West

Sales                                   $ 350,000  $ 620,000   $ 530,000

Variable expenses as

 a percentage of sales                44 %           39 %            49 %

Traceable fixed expenses $ 294,000  $ 329,000   $ 196,000

Implementation of the proposal:

Sales for West = $604,200 ($530,000 * 1.14)

Traceable fixed expenses for West = $225,000 ($196,000 + 29,000)

Contribution format income statement segmented by divisions:

                                               Company        East         Central         West

Sales                                    $ 1,574,200  $350,000  $620,000  $604,200

Variable expenses                   655,500     154,000      241,800    259,700

Contribution margin                  918,700  $196,000   $378,200  $344,500

Traceable fixed expenses        848,000   294,000    329,000    225,000

Non-traceable fixed expenses 110,000

Net operating income (loss) $ (39,300)  $(98,000)    $49,200   $119,500

Decrease in net operating loss = $45,200 ($84,500 - 39,300)

horsena [70]

Answer:

It will be counted as investment in 2016 and negative investment in 2017.

Explanation:

National income refers to the total value of a country's final output of all new goods and services produced in one year. There are various ways of measuring national income, e.g. GDP, GNP, etc

Therefore, following national income accounting practices, the car would be counted as part of the investments and GDP of 2016, and negative investment in 2017, because that was the year in which it was produced.

Answer:

Finland has a free-market economy

Explanation:

The fact that would most support this conclusion is that Finland has a free-market economy. A free market is an economic system characterized by a spontaneous and decentralized order of arrangements by individuals allowing them to make their own economic decisions based on supply and demand in that current time with little or no government control in the matter. This is an economic system that can only work in a developed economic nation.
