Answer:

There are 5 degrees of freedom.

Explanation:

If we want to find the degree of freedom in a chi-square check, the sample size was ' n ' then the number of degrees of freedom to be used in measurements would be n-1.

For a sample size of N=6, measure the degrees of freedom. Subtract 1 (df=6-1=5) from 6. of freedom in chi- square test .

  • Degree of freedom = (N-1).
  • Degree of freedom = (6-1)
  • Degree of freedom = (5)

therefore, the value of df is 5.

ArbitrLikvidat [17]

Answer:

Instructios are listed below

Explanation:

Giving the following information:

Assume Pinkie started the year with 100 containers of ink​ (average cost of $ 9.10 ​each, FIFO cost of $ 8.60 ​each, LIFO cost of $ 8.00 ​each).

During the​ year, the company purchased 800 containers of ink at $10.00 and sold 600 units for $21.75 each. Pinkie paid operating expenses throughout the​ year, a total of $ 5,000.

FIFO:

Sales= 600*21.75= 13,050

COGS= (100*8.60 + 500*10)= 5860

Gross profit= 7190

Operating expense= 5000

Net operating profit= $2,190

LIFO:

Sales= 13,050

COGS= (600*10)= 6000

Gross profit= 7,050

Operating expense= 5000

Net operating profit= $2,050

Average-cost

Sales= 13,050

COGS= [(9.10+10)/2]*600= 5730

Gross profit= 7,320

Operating expense= 5000

Net operating profit= $2,320

This is generally achieved by low operating costs and by the factors listed out in the example itself (influencing rivals and suppliers). This type of strategy puts a company ahead of most of its competitors.
