Question

An illustration shows a scatterplot with 25 points in quadrant 1. The x-axis is labeled daily high temperature and ranges from 60 to 95 degrees. The y-axis is labeled daily sales and ranges from 25 to 95 dollars. The x-axis shows temperature values in 5 degree increments. The y-axis shows sales in 10 dollar increments. The approximate coordinates of the points are as follows: left parenthesis 58 comma 23 right parenthesis, left parenthesis 60 comma 34 right parenthesis, left parenthesis 64 comma 19 right parenthesis, left parenthesis 66 comma 58 right parenthesis, left parenthesis 69 comma 43 right parenthesis, left parenthesis 69 comma 53 right parenthesis, left parenthesis 72 comma 48 right parenthesis, left parenthesis 74 comma 49 right parenthesis, left parenthesis 75 comma 49 right parenthesis, left parenthesis 77 comma 54 right parenthesis, left parenthesis 78 comma 57 right parenthesis, left parenthesis 78 comma 65 right parenthesis, left parenthesis 80 comma 54 right parenthesis, left parenthesis 81 comma 68 right parenthesis, left parenthesis 82 comma 63 right parenthesis, left parenthesis 84 comma 74 right parenthesis, left parenthesis 84.5 comma 67 right parenthesis, left parenthesis 85 comma 80 right parenthesis, left parenthesis 87 comma 74 right parenthesis, left parenthesis 88.5 comma 73.5 right parenthesis, left parenthesis 87.5 comma 95 right parenthesis, left parenthesis 91 comma 76 right parenthesis, left parenthesis 92.5 comma 69 right parenthesis, and left parenthesis 94 comma 86 right parenthesis, and left parenthesis 94.5 comma 80 right parenthesis.

Using the trend line, what whole number could you infer the daily sales amount is when the temperature is 68°? Round your answer to the nearest whole number.

Answer 1

To infer the daily sales amount when the temperature is 68 degrees using the trend line from the scatterplot, we can look for the approximate point that corresponds to 68 degrees on the x-axis.

Based on the data points you provided, the point (66, 58) indicates a sales amount of $58 at a temperature of 66 degrees, and (69, 43) shows a sales amount of $53 at a temperature of 69 degrees.

Between these two points, we can estimate a tentative sales amount for 68 degrees. Since 68 degrees is closer to 66 than to 69, we might expect that the sales amount would be a little higher than $58, but less than $53.

By estimating the trend, it seems reasonable that daily sales at 68 degrees would be around $56. Therefore, rounding to the nearest whole number, we can infer that the daily sales amount for a temperature of 68 degrees is approximately $55.
