Answer:
D. We are 95% confident that between about 22% and 28% of ESPN Viewers thought the Eagles would still win the division.
Step-by-step explanation:
We have to calculate a 95% confidence interval for the population proportion. The population is made up of ESPN viewers.
The sample proportion is p=0.25.
The standard error of the proportion is:
The critical z-value for a 95% confidence interval is z=1.96.
The margin of error (MOE) can be calculated as:
Then, the lower and upper bounds of the confidence interval are:
The 95% confidence interval for the proportion of ESPN viewers is (0.222, 0.278) or (22.2%, 27.8%).
