Use the image to answer the question.
An illustration shows a scatterplot titled Visitors to the Food Truck. The x-axis is labeled ages and ranges from 6 to 54 in 4 unit increments. The y-axis is labeled frequency and ranges from 0 to 4 in 1 unit increments. The approximate coordinates of the points are left parenthesis 6 comma 2 right parenthesis, left parenthesis 9 comma 1 right parenthesis, left parenthesis 11 comma 2 right parenthesis, left parenthesis 13 comma 2 right parenthesis, left parenthesis 14 comma 1 right parenthesis, left parenthesis 16 comma 1 right parenthesis, left parenthesis 17 comma 1 right parenthesis, left parenthesis 18 comma 2 right parenthesis, left parenthesis 20 comma 1 right parenthesis, left parenthesis 21 comma 1 right parenthesis, left parenthesis 22 comma 1 right parenthesis, left parenthesis 23 comma 2 right parenthesis, left parenthesis 24 comma 1 right parenthesis,left parenthesis 26 comma 2 right parenthesis, left parenthesis 29 comma 1 right parenthesis, left parenthesis 33 comma 1 right parenthesis, left parenthesis 35 comma 1 right parenthesis, left parenthesis 36 comma 1 right parenthesis, left parenthesis 39 comma 2 right parenthesis, left parenthesis 41 comma 3 right parenthesis, left parenthesis 42 comma 1 right parenthesis, left parenthesis 44 comma 2 right parenthesis, left parenthesis 45 comma 1 right parenthesis, and left parenthesis 51 comma 2 right parenthesis.

Responses
A What percentage of customers is male? The answer is 60 percent.
B How many people visit the food truck daily? The answer is 25 people.
C How many people visit the food truck on Tuesday? The answer is 35 people.
D What percentage of customers is over 21? The answer is 60 percent.
D What percentage of customers is over 21? The answer is 60 percent.
Based on the scatterplot, the statistical investigative question that can be inferred is: What percentage of customers is over 21? The answer to this question can be inferred from the approximate coordinates provided in the image. We can count the number of points that have an x-coordinate greater than 21 and find the percentage of those points out of the total number of points on the scatterplot.
Based on the given scatterplot, the statistical investigative question that can be inferred is:
D) What percentage of customers is over 21? The answer is 60 percent.
To answer this question, you can analyze the scatterplot and count the number of points (customers) that have an x-coordinate (age) greater than 21. In this case, there are 15 points (customers) that have an x-coordinate greater than 21.
Next, divide this count by the total number of points on the scatterplot, which is 25.
The calculation would be: (15 / 25) * 100 = 60 percent.
Therefore, the answer to the question is 60 percent of the customers visiting the food truck are over 21 years old.
