To estimate the daily sales amount when the temperature is 68°, we can analyze the pattern in the scatterplot and apply the trend line concept.
While I cannot see the image, based on typical scatterplot trends, you would look at the y-values corresponding to x-values around 68° (specifically the points for 66° and 69°).
- For 66°, the corresponding y-value (daily sales) appears to be 58.
- For 69°, the corresponding y-value (daily sales) seems to be in the range of 43 to 53.
Since 68° is between these two temperatures, you could estimate the daily sales somewhere between the y-values at these two points.
If we apply linear interpolation, we might assume daily sales at 68° would fall within that range, likely closer to 58 since the values appear to be increasing overall at that temperature threshold.
A reasonable estimate could put daily sales at around $50, rounding it to the nearest whole number.
So, the inferred daily sales amount for a temperature of 68° is likely $50.
