Analyzing Data Practice 1

Antibiotics kill bacteria. The CDC has seen an outbreak of antibiotic-resistant bacteria from Monita farms. Monita farms have antibiotics in their animal feed. A study was conducted to compare antibiotic resistance in the bacteria at Monita farm to the control farm, where the animal feed does not contain antibiotics, to see what is causing the outbreak. What is the purpose of this study? To determine what is causing the antibiotic resistant bacteria outbreak. To increase the population of antibiotic resistant bacteria. To create stronger antibiotics. A title of a graph tells you what the graph is about. What is the graph below about? The number of bacteria at Monita farms. The amount of antibiotics at Monita farms. The y axis of a graph shows what is being measured. Based on the graph, what is being measured? Percentage of alive bacteria Percentage of antibiotics Types of antibiotics Types of bacteria The x-axis represents the independent variable that is affecting what is being measured. What is the independent variable in this experiment? The percentage of alive bacteria. The percentage of antibiotics. The types of antibiotics used. The types of bacteria observed. The control of an experiment is when the independent variable is not used. It serves as a point of comparison to make sure the experiment is working. In this experiment, the control bacteria did not receive any antibiotics. What would you expect the percentage of alive bacteria to be in the control? 0% 50% 75% 100% Which of the statements about the graph is true? (select all that apply) 100% of the bacteria are alive in the control. Antibiotics 1-5 killed over 50% of the bacteria. Over 90% of bacteria are alive after use of antibiotics 1-5. Which statements about the graph are true? (select all that apply) The 5 different antibiotics killed about 50% of the bacteria. Only 50% of the bacteria are alive after use of antibiotics. Over 90% of bacteria are alive after use of antibiotics 1-5. Antibiotics kill bacteria. The CDC has seen an outbreak of antibiotic-resistant bacteria from Monita farms. Monita farms have antibiotics in their animal feed. A study was conducted to compare antibiotic resistance in the bacteria at Monita farm to the control farm, where the animal feed does not contain antibiotics, to see what is causing the outbreak.How is Monita farm different from the Control farm? Monita farms contains antibiotics in their animal feed and the control farm does not. The control farm contains antibiotics in their animal feed and Monita farm does not. Compare the 2 graphs. Which statement is true according to the graphs? The bacteria at Monita farm are more resistant to the antibiotics than the bacteria at the control farm. The bacteria at the control farm are more resistant to antibiotics than the bacteria at Monita farms. Which of the following BEST explains why there is greater antibiotic resistance at Monita farms? The antibiotics used at Monita farms mutated the bacteria to be antibiotic resistant. The overuse of antibiotics in the animal feed at Monita farm caused non-resistant bacteria to die off and resistant bacteria continued to survive and reproduce. The overuse of antibiotics at the Control farm caused non-resistant bacteria to die off and resistant bacteria continued to survive and reproduce. The bacteria at Monita farms became used to the antibiotics found in the animal feed and developed resistance over time.
