Answer:

Yes, because only people entering the mall were given the survey

Step-by-step explain

Out of the people that entered, the mall 215 of them returned the survey, this makes sense to choose this answer, because a large population of the people who entered returned the survey, and it was randomly given out

The result of the survey can be generalized if the sample is representative

of the population making the study useful to the population.

Should the result be generalized to all customers of the shopping mall?

No, because a random sample from all customers of the shopping mall was not selected.

Reasons:

Some important factors for making generalization from a sample are;

  • The usefulness of the study result to the general population.
  • The use of a representative sample for the survey.
  • The sample size of the participants

The above requirements, indicates that the use of a representative sample of all customers is required for the generalization of the results.

Therefore, given that the survey is based on only;

  • The customers that walk through one of the doors of the mall, rather than all the entrances to the mall
  • The customers that shopped at the mall on the day of the survey is, not including  customers that shop on other days, such as weekends
  • The customers that  walk into the stores not including the online customers

The participant of the survey are not representative of the population. The

condition of a random sample of all customers of the shopping mall to be

included in the survey is not met, and therefore;

The result of the survey should not be generalized to the population of all

customers of the shopping mall, because a random sample was not used in

the survey.
