The state and local police departments are trying to analyze crime rates so they can shift their patrols from decreasing-rate ar

eas to areas where rates are increasing. The city and county have been geographically segmented into areas containing 5,250 residences. The police recognize that not all crimes and offenses are reported: People do not want to become involved, consider the offenses too small to report, are too embarrassed to make a police report, or do not take the time, among other reasons. Every month, because of this, the police are contacting by phone a random sample of 1,000 of the 5,250 residences for data on crime.
(Respondents are guaranteed anonymity.) Here are the data collected for the past 12 monthsfor one area:
Construct a p-chart for 95 percent confidence (1.96) and plot each of the months. If the next three months show crime incidences in this area as
January =10 (out of 1,000 sampled)
February = 1 2 (out of 1,000 sampled)
March = 11 (out of 1,000 sampled)
What comments can you make regarding the crime rate?

Answer:

= 0.008

Explanation:

Base on the scenario been described in the question , to develop a p-chart, first calculate as shown below:

P bar= total number of defective units from all samples /(number of samples ×sample size)

= 100/(12×1000)

= 100/12000

= 0.008

Thus, the p bar is 0.008

What are the main factors that affect the amount of business competition?
aliina [53]

Answer:

From a microeconomics perspective, competition can be influenced by five basic factors: product features, the number of sellers, barriers to entry, information availability, and location. Each factor hinges on the availability or attractiveness of substitutes and, when no alternatives exist and the company is a single seller of a unique product, a monopoly exists and there is zero competition.

Explanation:

  • When a company has a unique product that no other company is selling, a monopoly exists, as there is no competition.
  • Most markets are somewhere in between competition and a monopoly.
  • The amount of competition will also vary depending on location, the barriers to entry, and the availability of pricing information.

Alternatively, a product might be completely differentiated, meaning that it is unique. If so, there might be few alternatives and thus low levels of competition. The level of differentiation is largely a subjective matter and subject to consumer opinion.

The number of sellers also impacts competition. If there are many sellers of an undifferentiated product, competition is considered to be high. If there are few sellers, competition is low. If there is a single seller, the market is considered a monopoly.
