Of the 1002 surveyed, 530 stated that they were worried about having enough money to live comfortably in retirement. Construct a 95% confidence interval for the proportion of adults who are worried about having enough money to live comfortably in retirement.

There is a 95% probability that the true proportion of worried adults is between andSleep apnea is a disorder in which you have one or more pauses in breathing or shallow breaths while you sleep. In a cross-sectional study of 400 adults who suffer from sleep apnea, it was found that 240 had gum disease. Note: In the general population, about 17.5% of individuals have gum disease.
