Titanic A study was conducted of all 2223 passengers aboard the Titanic when it sank.

Short Answer

Expert verified

For a study, the value of 2223 representing the total number of passengers aboard the Titanic is a parameter.

Step by step solution

01

Given information

The total number of passengers who were on the Titanic is equal to 2223.

02

Statistic and parameter

A numerical value that is computed from the population and used to describe it is called a parameter. For example, the total number of households (in lakhs) in Los Angeles is equal to 14. The value 14 represents the size of the population, so this is a parameter.

A numerical value that is computed from the sample and used to describe it is called a statistic. For example, a sample of 600 restaurants in the United States is selected for a study. The value 600 represents the sample size, so this is a statistic.

03

Identification of a statistic or a parameter

Since 2223 is the size of the entire group of passengers on the Titanic, it is aparameter.

There is a 0.3% chance of getting those results by chance. Does the course appear to be effective?

The entries are white blood cell counts (1000 cells,ML) and red blood cell counts (million cells,ML) from male subjects examined as part of a large health study conducted by the National Center for Health Statistics. The data are matched, so that the first subject has a white blood cell count of 8.7 and a red blood cell count of 4.91, and so on.

Context Given that the data are matched and considering the units of the data, does it make sense to use the difference between each white blood cell count and the corresponding red blood cell count? Why or why not?
