To gain a better understanding of the production process, Tom decided to use p-chart to monitor and identify the assignable cause variations. For the next 8 working days, Tom collected 8 samples (each of the size 100 units) and found the following number of defects, 4, 6, 0, 1, 3, 5, 8, 3.
a. What is the defect rate for sample 2? Ignore the percentage sign, and round your answer to the nearest integer. For example, if your answer is 12.34%, input 12.

Your answer is .

b. What is p-bar? Ignore the percentage sign, and round your answer to two decimals. For example, if your answer is 12.34%, input 12.34. (Note that this is different from question a.)

d. What is upper control limit UCL for this p-chart? Ignore the percentage sign, and round your answer to two decimals. For example, if your answer is 12.34%, input 12.34.

Your answer is .

e. What is lower control limit LCL? (If LCL is negative, input 0) Ignore the percentage sign, and round your answer to two decimals. For example, if your answer is 12.34%, input 12.34. If your answer is -1.234%, input 0.

Answer:

Answer a= Defect rate of sample 2= 6/100 =6

Answer b=

Data  % defect % defect

4      4/800            0.005

6     6/800           0.0075

0     0/800                 0

1      1/800           0.00125

3      3/800           0.00375

5      5/800           0.00625

8      8/800              0.01

3     3/800          0.00375

Sum            0.0375

p bar =0.0375

Answer c= sigma = [p bar(1-p bar) / sample size]]0.5

Sigma = (0.0375*(1-0.0375)/100)^0.5 =0.019

Answer d= UCL=p bar + 3*(Estimated standard deviation) = 0.0375+3*0.019 =0.0945

Answer e= LCL=p bar - 3*(Estimated standard deviation) =0.0375-3*0.019 =-0.0195=0

Masteriza [31]

For each of the following scenarios, identify the number of firms present, the type of product, and the appropriate market model
marshall27 [118]

Answer:

Number of Firms - many

Type of Product - differentiated

Market Model - monopolistic competition

Number of Firms - many  

Type of Product - standardised  

Market Model - perfect competition

Number of Firms - few  

Type of Product - standardised  

Market Model - oligopoly

Number of Firms - one

Type of Product - unique

Market Model - monopoly

Explanation:

A perfect competition is characterized by many buyers and sellers of homogenous goods and services. Market prices are set by the forces of demand and supply. There are no barriers to entry or exit of firms into the industry.   In the long run, firms earn zero economic profit.  If in the short run firms are earning economic profit, in the long run firms would enter into the industry. This would drive economic profit to zero.  

Also, if in the short run, firms are earning economic loss, in the long run, firms would exit the industry until economic profit falls to zero.  

A monopolistic competition is when there are many firms selling differentiated products in an industry. A monopoly has characteristics of both a monopoly and a perfect competition. the demand curve is downward sloping. it sets the price for its goods and services.

An example of monopolistic competition are restaurants  

A monopoly is when there is only one firm operating in an industry. there are usually high barriers to entry of firms. the demand curve is downward sloping. it sets the price for its goods and services.

An example of a monopoly is a utility company

An Oligopoly is when there are few large firms operating in an industry. While, a monopoly is when there is only one firm operating in an industry.

Oligopolies are characterised by:

  • price setting firms  
  • profit maximisation
  • high barriers to entry or exit of firms
  • downward sloping demand curve
