Question

A city ballot includes a local initiative that would legalize gambling. The issue is hotly contested, and two groups decide to conduct polls to predict the outcome. The local newspaper finds that 53% of 1200 randomly selected voters plan to vote "yes," while a college statistics class finds that 54% of 450 randomly selected voters in support.

Once of the groups concludes the outcome is too close to call. Which group and why?

A) The newspaper since their point estimate is lower.
B) The statistics class since their point estimate is higher.
C) The statistics class since the lower bound of their confidence interval is below 50%.
D) The newspaper since the lower bound of their confidence interval is just above 50%.
E) It is impossible to determine with the given information.

Is the answer D? I am struggling with this question. Thanks.

Answer 1

Conclude that their interval is too close to call because 50% is in the interval, meaning that it is quite likely that p could be 50%.

Answer 2

Thank you, but I'm still confused. So is there not enough info to answer this question? Thank you for your time.
