The population is all the adults

Sample is "1046" adults selected for survey

Step-by-step explanation:

* Lets revise some definitions

- Population is the complete collection of data that are being considered

- Ex: The population may be "ALL people living in the US"

- A sample is a sub-collection of members selected from a population

- The size of a sample is always less than the size of the population from

  which it is taken

- Ex: The sample may be "some people living in the US"

* Lets solve the problem

- There is a survey of 1046 adults conducted by Bradley Corporation,

  subjects were asked how often they wash their hands when using a

  public restroom

- 70% of the respondents said "always."

* We need to identify the sample and population

- According to the definition above

# The population is all the adults

# Sample is "1046" adults selected for survey
