Several studies showed that after accessing the internet for schoolwork, subjects had an increase in grades. A broadband internet provider financed this research. Identify what is wrong. Choose the correct answer below. A. The data used in the studies is not reliable because it was not measured by the administrator. B. It is questionable that the sponsor is a broadband internet provider because this sponsor can be greatly affected by the conclusion. C. It is not possible to take accurate measurements. D. Since the research is composed of voluntary response samples, there may be key data points missing.

B. It is questionable that the sponsor is a broadband internet provider because this sponsor can be greatly affected by the conclusion.

Step-by-step explanation:

From this research, the increase in grades of subjects could have been due to materials or other journals accessed on the internet rather than the usage of internet. Because if appropriate materials were not accessed by subjects on the internet, probably the increase would not have been achieved.

Thus, the conclusion of the study could have been influenced by the internet provider so as to encourage subjects to believe that using the internet increases grade. This would then increase exponentially the number of subjects that would subscribe to his services.
