Which of the following describes a scenario in which a chi-square goodness-of-fit test would be an appropriate procedure to justify the claim? A statistician would like to show that one geographical location has a higher proportion of dogs that shed than another geographical location has. The statistician has two independent random samples of dogs from two different geographical locations and has recorded the proportion of dogs that shed in each sample. A A principal would like to investigate whether more than 50% of the students in a local high school eat in the school cafeteria. The principal has a random sample of individuals within the school B and records the proportion of the students who eat lunch in the school cafeteria. A campaign manager would like to show that the distribution of individuals within several social economic categories is different than what a newspaper reported. The campaign manager has a random sample of potential voters in a large city and records the number of individuals within each of the categories. A manager of a water treatment plant would like to investigate whether there is a relationship between the amount of chemical used and the number of bacteria present in the water treated at the plant. The manager measures the level of bacteria from tanks at the facility that each received a different level of chemical treatment. E City officials would like to estimate the average price of gas in their city. The officials have a random sample of gas prices at several gas stations within their city limits.
