To infer the approximate daily sales amount when the temperature is 68°, you would need to look at the trend line (which is not visible here) that is fitted to the scatterplot data points. Based on the coordinates you provided around the temperature of 68°, you can see that there are points with y-values (daily sales) around that temperature.
Given the coordinates provided:
- At 66°, the sales are 58 dollars.
- At 69°, the sales are around 43 or 53 dollars (two points).
- There's also a point at 72° with sales of 48 dollars.
From this, we can make an educated guess. The sales amount for 68° is likely between the sales figures for 66° and 69°. A rough estimate would suggest that the sales amount might be around 50 dollars when interpolating between the points.
Therefore, rounding to the nearest whole number, the inferred daily sales amount when the temperature is 68° could be approximately:
$50.
