ANSWER:

Mean: 512 calories

Median: 550 calories

Explanation:

The first thing is to determine the data necessary to calculate the mean and median, according to the statement, the data is as follows:


560,400,400,570,570,570,570,570,450,450,450,450,450,450,550,550,550,550,550,550,550

The mean is the average value of a set of numeric data, calculated as the sum of the set of values divided by the total number of values:


\begin{gathered} m=(560+400+400+570+570+570+570+570+450+450+450+450+450+450+550+550+550+550+550+550+550)/(21) \\ m=(10760)/(21)=512.38\cong512 \end{gathered}

The median is a central position statistic that splits the distribution in two, that is, it leaves the same number of values on one side as on the other. To calculate the median it is important that the data are ordered from highest to lowest, or conversely from lowest to highest, therefore, we organize:


400,400,450,450,450,450,450,450,550,550,550,550,550,550,550,560,570,570,570,570,570

The value in the middle after arranging is 550, therefore the median is 550 calories.
