13. In a recent survey, a random sample of OSU football fans was asked if they would consider dating someone who is a fan of a rival football team. Based on the proportion who answered “yes” to this question, a 95% confidence interval was constructed, and this interval was from 0.66 to 0.80. From this information, we can conclude that 1. there is a 5% chance a mistake was made when constructing the confidence interval. 2. the margin of error is equal to 0.05. 3. if you randomly select one OSU football fan, there is a 95% chance that fan would consider dating someone who is a fan of a rival football team. 4. the population proportion is definitely between 0.66 and 0.80. 5. more than half of the sample said they would consider dating a fan of a rival team.
