Question

which data value would cause the interpretation of the data set to be understated? (20, 1) (55, 6) (90, 2) (95, 8)

Explanation:

Step1: Identify the general trend

From the scatter - plot, as the outside temperature increases, the number of hours at the pool generally increases.

Step2: Analyze each data point

• For the point \((20,1)\): It is in line with the initial low - temperature and low - hour trend.
• For the point \((55,6)\): It is within the range of the increasing trend.
• For the point \((90,2)\): When the temperature is relatively high (\(90^{\circ}F\)), the number of hours (\(2\)) is much lower than what the general increasing trend would suggest. This is an outlier that would understate the relationship (as the trend is that hours increase with temperature).
• For the point \((95,8)\): It follows the increasing trend.

Answer:

\((90, 2)\)
