The difference between the sample statistic and population parameter is called:_______
myrzilka [38]

Answer:

The difference between the sample statistic and population parameter is called sampling error.

Step-by-step explanation:

We are given the following in the question:

  • A sample is a part of population, it is a subset of population.
  • A sample statistic describes the sample. It is a characteristic of sample and different from the population.
  • A parameter describes the population. It is characteristic of a population.
  • A sample may not be able to represent the whole population and this may lead to error.
  • Thus, sampling error is the difference between the sample statistic and population parameter.
  • It arises when the sample is not able to describe the population.

The difference between the sample statistic and population parameter is called sampling error.

Find the markup and the cost of the following item. Round answers to the nearest cent.
marysya [2.9K]

Answer:

1st question: M=22.62 while C=75.38

2nd question: M=.22 while C=1.97

Step-by-step explanation:

If a mirror costing x dollars is marked up 30%, then we have to find x such that 30%x+x is 98 dollars.

We are solving:

.3x+x=98

Combine like terms:

1.3x=98

Divide both sides by 1.3:

x=75.38

M=98-75.38=22.62

C=75.38

So M=22.62 while C=75.38.

If ream of paper cost x and is marked up 11%, then we have to find x such that 11%x+x is 2.19.

We are solving:

.11x+x=2.19

1.11x=2.19

x=1 97

M=2.19-1.97=.22

So M=.22 while C=1.97
