Question 16 In cardiac muscle, calcium ions are not released from the sarcoplasmic reticulum. calcium ions do not bind to troponin molecules. calcium ions play no role in the process of contraction. some of the calcium ion required for contraction comes from outside of the cell. calcium ion plays a greater role in reploarization than sodium and potassium. Question 17 Stretching a myocardial cell decreases the force of a contraction. allows more $Ca^{2+}$ to enter. increases the force of contraction. decreases the force of a contraction and allows more $Ca^{2+}$ to enter allows more $Ca^{2+}$ to enter and increases the force of contraction. Question 18 The first heart sound is heard when the AV valves open. the AV valves close. the semilunar valves close. the atria contract. blood enters the aorta.

You wish to determine if there is a positive linear correlation between the two variables at a significance level of $\alpha = 0.01$. You have the following bivariate data set. \begin{tabular}{ |c|c| } \hline x & y \\ \hline 32.9 & 78.1 \\ 31.7 & 33 \\ 36.4 & 91.4 \\ 51.9 & 104.8 \\ 40.1 & 77.2 \\ 59.6 & 64.6 \\ 71.8 & 189.6 \\ 43.5 & 67.9 \\ 31.5 & 57.6 \\ 21.6 & 34.8 \\ 82.3 & 87.6 \\ 30.1 & 61 \\ 28.8 & 44.8 \\ 50.4 & 84.1 \\ 49.3 & 70.6 \\ 27 & 56.7 \\ 45.3 & 51.1 \\ 56.9 & 49.9 \\ 22.7 & 51.1 \\ 47.9 & 64.2 \\ 51.1 & 107.7 \\ 19.8 & 54.4 \\ 44.1 & 18.8 \\ 16.6 & 27.4 \\ 45.8 & 78.1 \\ 50 & 47.9 \\ 44.8 & 70.4 \\ 24.3 & 42.5 \\ \hline \end{tabular} download link provided here: Download CSV What is the correlation coefficient for this data set? $r = $ (report answer accurate to at least 3 decimal places) To find the p-value for a correlation coefficient, you need to convert to a t-score: $t = r \cdot \sqrt{\frac{n-2}{1-r^2}}$ This t-score is from a t-distribution with $n-2$ degrees of freedom. What is the p-value for this correlation coefficient? p-value = (report answer accurate to at least 4 decimal places) Your final conclusion is that... There is sufficient sample evidence to support the claim that there is a statistically significant positive correlation between the two variables.
