Using the data presented, answer the questions below.
A researcher is interested if the number of pets people own (the \( x \)-variable) is related to their stress on a scale of 0-60 (the \( y \)-variable). Note: Please enter all values as numbers (1,2,3), not words (one, two). Please include at least three places after the decimal point in all your work and answers (where relevant), to avoid rounding error.
A data table for \( X \) and \( Y \) variables
\[
x=\text { pets } \quad y=\text { stress }
\]

Person 2 1 50
Person 3 3 30

What is total N? \( \square \)
- The mean for pets \( (\mathrm{x}): \hat{\mathrm{x}}=2.2 \)
- What is the mean for stress \( (y): \bar{y}= \) \( \square \)
- The standard deviation for stress \( (\mathrm{y}): \mathrm{S}_{\mathrm{y}}=11.402 \)
