Step-by-step explanation:
The subject of this question is Mathematics and it is targeting students in High School. The question asks for the correct answer regarding the mean percentage of a population of people eating out at least once a week, which is given as 57.
To find the probability associated with this mean, we need additional information such as the standard deviation or sample size. Without this information, it is not possible to calculate the probability asked in Question 57.
