Final answer:
The proportion of students who watched the game with a 95% level of confidence is 'more than 50%' as it is the only option that falls within the 49% to 55% range provided by a national survey mentioned.
Step-by-step explanation:
To determine which option presents a possible proportion of students who watched the game with a 95% level of confidence, we can refer to a given confidence interval from a survey. If a national survey concluded with 95 percent confidence that 49 percent to 55 percent of Americans believe that major college sports programs corrupt the process of higher education, we understand that the proportion is somewhere between these two percentages.
Considering the provided options, 60%, 65%, and 45% fall outside this range, while 'more than 50%' includes 55%, but does not exclusively indicate any specific value beyond that. Therefore, the only proportion that falls within the 49% to 55% range is 'more than 50%', understanding it as implying any proportion greater than 50% but not exceeding 55%. However, it is important to note that this is a general interpretation and the precise question context might be needed for a definitive answer. With respect to the confidence level, if a point estimate falls within a confidence interval, we can say with that level of confidence the proportion is expected to be within that range.
