The article reports that in a random sample of 1760 residents of the city, 597 answered "yes" to the following question: "Are you satisfied with the ecological situation in your city?" The authors were interested in using these data to determine if there is convincing evidence that less than 40% residents of the city are satisfied with the ecological situation in the city. Answer the following four key questions and indicate whether the method that you would consider would be a large-sample hypothesis test for a population proportion.
A)Hypothesis testing, sample data, one categorical variable, one sample.A large-sample hypothesis test for a population proportion would not be appropriate.
B)Estimation, sample data, one numerical variable, one sample.A large-sample hypothesis test for a population proportion would be appropriate.
C)Hypothesis testing, sample data, one numerical variable, one sample.A large-sample hypothesis test for a population proportion would not be appropriate.
D)Estimation, sample data, two categorical variables, one sample.A large-sample hypothesis test for a population proportion would be appropriate.
E)Hypothesis testing, sample data, one categorical variable, one sample.A large-sample hypothesis test for a population proportion would be appropriate.
