To determine how many observations Dakota recorded, let's analyze the data table provided:
[tex]\[
\begin{tabular}{|l|l|l|l|}
\hline \multicolumn{4}{|c|}{ Days of Running per Week } \\
\hline 7 & 5 & 3 & 1 \\
\hline 6 & 4 & 7 & 5 \\
\hline 1 & 3 & 2 & 4 \\
\hline 3 & 4 & 1 & 2 \\
\hline
\end{tabular}
\][/tex]
Each cell in the table represents one observation of the number of days a classmate runs in a typical week.
First, let's count the number of rows in the table:
There are 4 rows.
Now, let's count the number of columns in each row:
Each row has 4 columns.
Since there are 4 rows and 4 columns, the total number of observations is calculated by multiplying the number of rows by the number of columns.
[tex]\[
4 \text{ rows} \times 4 \text{ columns} = 16 \text{ observations}
\][/tex]
Therefore, Dakota recorded a total of 16 observations.
The correct answer is:
A. 16
