This statement means that we can be 90% confident that the true population percentage falls within the interval from 30% to 38%. It does not mean that 90% of the samples fall within this range or that there's a 90% probability of the population percentage being within this specific interval. Confidence intervals provide a range of values that likely contain the population parameter, with a specified level of confidence (in this case, 90%).
