The opinions, shown in a random order to each buyer, were as follows: Opinion A: Improving the healthcare system is more important than improving the education system.

If they felt neutral on the topics, they were to choose a third option of "Neutral." The outcomes were as follows: 39% chose Opinion A, 54% chose Opinion B, and 7% chose "Neutral." Part A: Create and interpret a 98% confidence interval for the proportion of all US buyers of this particular app who would have chosen Opinion B.
