Use the following observations to calculate the statistics below. Assume the data is from a sample. \[ x_{1}=24, x_{2}=19, x_{3}=23 \] What is the sample standard deviation? 22 5 \( 2.646 \) \( 3.445 \) Calculate the sample correlation coefficient for the data below. Assume the data comes from a sample. The sample standard deviation for variable \( \mathrm{X} \) is 5 and for variable \( \mathrm{Y} \) is \( 5.033 \). \begin{tabular}{ll} \( X \) & \( Y \) \\ 5 & 8 \\ 10 & 18 \\ 15 & 14 \\ \hline \end{tabular} \( 1.25 \) \( -0.623 \) \( 0.596 \) \( 0.498 \) Calculate the sample covariance for the data below. Assume the data comes from a sample. 12 15 23 5
