a) Make a scatterplot of the data above. (2 points)

b) Do you notice clusters or outliers in the data? Explain your reasoning. (2 points)

c)How would you describe the correlation in the data? Explain your reasoning. (2 points)

d) What are the independent and dependent variables? (2 points)

Step 2: Evaluating trends of data

Because you want to prepare and serve the healthiest food possible, you monitor the fat and calorie content of items on your menu. Some of the menu items are included in the graph below.

a)Your business partner describes this as a high positive correlation. Is your partner correct? Why or why not? (2 points)

b)Using the drawing tools, draw a trend line (line of best fit) on the graph above. (2 points)

c)Judge the closeness of your trend line to the data points. Do you notice a relationship between the data points? (2 points)

d)Is the trend line linear? If so, write a linear equation that represents the trend line. Show your work. (3 points)

Step 3: Making predictions using data

You and your business partner track the number of customers served and the amount of tips collected per day. The data you gathered is displayed in the chart below.
