1.Is this a Positive Linear, Negative Linear, or Nonlinear association?
2. Write an equation for the trend line:
3. Define an outlier and a cluster? How would you recognize it on a scatter plot?
4. Find missing number in frequency table. Then find the relative frequency that if you play sports in the winter, it will be baseball. Round to nearest tenth percent.
5. Make a scatter plot of this data and draw a best fit line
Month 1 2 3 4
Number of slushies sold 15 22 26 28
1. This is a Positive Linear association.
2. The equation for the trend line is y = 4.25x + 10.
3. An outlier is a data point that differs significantly from the rest of the data. It can be recognized on a scatter plot by being far away from the other data points. A cluster is a group of data points that are close to each other on the scatter plot.
4. The missing number in the frequency table is the number of people who play sports in the winter and play baseball. Assuming there is a total of 100 people, the missing number can be calculated as (15+22+26+28) - (12+10+14) = 4. The relative frequency of playing baseball if you play sports in the winter is 4/100 = 4%.
5. (Unable to provide a visual image, but please plot the data points Month vs. Number of slushies sold on a graph and draw the best fit line.)
