Answer 1

The question is about confidence intervals and margin of error, indicating that we can be 90% confident the true population proportion expecting to inherit lies between 23% and 33%.

Step-by-step explanation:

The student's question relates to confidence intervals and understanding the results of a poll within a margin of error. When a poll indicates that only 28% of American adults expect to inherit valuable possessions with a margin of error ±5 percentage points at a 90% confidence level, it means that we can be 90% confident that the true proportion in the population lies within the range of 23% to 33%.

This does not imply that the percent of all adults who expect an inheritance must be within this range, nor does it guarantee that repeated polls will always fall within this range. The method aims to capture the true population proportion within this interval 90% of the time. As such, only the first statement provided in the question is correct, stating there's a 90% chance that the percent of all adults who expect an inheritance is between 23% and 33%.
