Abigail is running a fundraiser for Love Week where students can buy a rose for somebody and someone will deliver it to that person on Valentine's Day. Abigail knows that red roses are the most common type of roses, but she is interested in whether students would also be interested in sending yellow roses to people since yellow roses are a sign of friendship. She surveyed 380 people and discovered that between 42.8% and 51.7% of students would be interested in sending yellow roses. What is the point estimate they used to create this interval? a. What confidence level did they use to create their confidence interval?
