The image contains a statistical problem involving evaluating the efficiency of a system with different concentrations of nitrogen expressed in \( x \), and the weight of onions in grams is measured as \( y \). There are two parts in the question:

1. Calculate the mean, standard deviation, and coefficient of variation for the variable \( y \).

Here's the dataset provided for \( x \) (concentration of nitrogen) and \( y \) (weight of onions):

\[
\begin{array}{|c|c|}
\hline
x & y \\
\hline
1 & 4 \\
2 & 5 \\
3 & 6 \\
4 & 7 \\
5 & 8 \\
6 & 9 \\
7 & 10 \\
8 & 11 \\
9 & 12 \\
10 & 13 \\
\hline
\end{array}
\]

Would you like me to calculate these statistics for \( y \) and provide detailed explanations for each?

We want to evaluate the efficiency of a system for onion production using different concentrations of nitrogen and the resulting weights of onions. The dataset provided gives values of nitrogen concentration (x) and onion weights (y). The task is to calculate the mean, standard deviation, and coefficient of variation for the variable y (onion weights).

Calculate the mean, standard deviation, and coefficient of variation for a dataset of nitrogen concentration and onion weights. This problem covers key statistical concepts and is suitable for students in Grades 9-12.
