Respuesta :
The company wanted to make sure that the population sample was completely random.
Every member of the population must have the same probability of being included in the sample distribution in order to obtain a sample that is truly representative of the larger population. If the company had only taken into account those with telephone lines, it would have indicated that a significant portion of the population was excluded on purpose and not by accident.
Members who do not have a telephone, on the other hand, have a random chance of being included in the sampling distribution when an online survey tool is used. resulting in a good representation of the larger population in the sampling distribution.
