A certain article indicates that in a sample of 1,000 dog owners, 610 said that they take more pictures of their dog than of their significant others or friends, and 420 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) 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. (Use a table or technology. Round your answers to three decimal places.) Interpret the interval. 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 within this interval. We are 90% confident 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. We are 90% confident that the true proportion of dog owners who take more pictures of their dog than of their significant others or friends falls within this interval. 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. 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. (b) Construct a 95% confidence interval for the proportion of dog owners who are more likely to complain to their dog than to a friend. (Use a table or technology. Round your answers to three decimal places.)

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Question
Transcribed Image Text:A certain article indicates that in a sample of 1,000 dog owners, 610 said that they take more pictures of their dog than of their
significant others or friends, and 420 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) 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. (Use a table or technology. Round your answers to three decimal places.)
Interpret the interval.
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 within this interval.
We are 90% confident 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.
We are 90% confident that the true proportion of dog owners who take more pictures of their dog than of their
significant others or friends falls within this 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.
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.
(b) Construct a 95% confidence interval for the proportion of dog owners who are more likely to complain to their dog than to a
friend. (Use a table or technology. Round your answers to three decimal places.)
