A certain article indicates that in a sample of 1,000 dog owners, 690 said that they take more pictures of their dog than their significant others or friends. In addition, 470 said that they are more likely to complain to their dog than to a friend. Suppose that it is reasonable to consider this sample as representative of the population of dog owners. A USE SALT (a) Construct a 90% confidence interval for the proportion of dog owners who take more pictures of their dog than of their significant others or friends. (Round your answers to three decimal places.) Interpret the interval. O We are 90% confident that the mean number of dog owners who take more pictures of their dog than of their significant others or friends falls within this interval. O There is a 90% chance that the true proportion of dog owners who take more pictures of their dog than of their significant others or friends falls directly in the middle of this interval.
