Use the image to answer the question.
A scatterplot shows the number of cups of coffee sold versus temperature.
The horizontal axis shows temperature, in degrees Fahrenheit, ranging from 0 to 70 in increments of 5, with an initial jump from 0 to 25. The vertical axis shows number of cups of coffee sold, ranging from 0 to 60 in increments of 10. A kink is shown on the horizontal axis close to origin. A tightly packed cluster of data plots is plotted between 30 to 37 on the horizontal axis and 42 to 48 on the vertical axis. A loosely packed cluster of data plots is plotted between 40 to 51 on the horizontal axis 30 and 38 on the vertical axis and. A dot is plotted at 62 on the horizontal axis and 5 on the vertical axis.
Numbers of Cups of Coffee Sold Versus Temperature
Interpret the scatterplot by describing any outliers and patterns of clustering.
(4 points)
In the scatterplot, there is one outlier, which is the dot plotted at 62 on the horizontal axis and 5 on the vertical axis. This outlier represents a high number of cups of coffee sold at a relatively high temperature.
There are two main patterns of clustering in the scatterplot. The first pattern is a tightly packed cluster of data plots between 30 to 37 on the horizontal axis and 42 to 48 on the vertical axis. This indicates that there is a consistent number of cups of coffee sold within this temperature range.
The second pattern is a loosely packed cluster of data plots between 40 to 51 on the horizontal axis and 30 to 38 on the vertical axis. This indicates that there is some variability in the number of cups of coffee sold within this temperature range.
Overall, the scatterplot shows that there is a positive relationship between temperature and the number of cups of coffee sold, with some variability in the data.
