The outlier present on the graph likely occurs due to an error in recording the data. If the outlier is removed, then the correlation coefficient (r) increases.
The correct option is option c.
In a particular experiment, the weights (readings taken in pounds) as well as the cholesterol levels (readings taken in mg/dl) of a number of individuals was observed. The data was then shown with the help of a scatterplot.
The outlier present on the graph is most likely as a result of an error which occurs during the recording of the data. The outlier will lie on the outside of the linear pattern which is basically formed by most of the data. Since correlation happens to measure how tightly the points that are present in a graph happen to cluster about a straight line, then removing of the outlier, which happens to have the largest deviation from the straight line will end up increasing the correlation coefficient.

Identify two characteristics of the SA node cardiomyocytes that contribute to its automaticity.
The SA node produces 100–110 action potentials or "beats" each minute of intrinsic automaticity spontaneous pacemaker activity.
The group of cells known as the sinus node, also called the SA node, acts as the heart's natural pacemaker. This cells' automaticity causes them to depolarize on their own. The remainder of the heart is then affected by the depolarizing impulses produced by the SA node.
The upper heart chambers contract as a result of an electrical signal produced by the SA (sinoatrial) node. The lower heart chambers then contract or pump as a result of the signal as it travels via the AV node. The SA node is regarded as the heart's pacemaker.

1 .
A correlational study found that the correlation between spousal relationship quality and
cardiovascular risk was -0.72.
Fully interpret the correlation (using he first three statements as in Chapter 9):
Calculate the percent of variance in cardiovascular risk accounted for by spousal relationship
quality (this is the same as the degree of relationship). Show your work.
% variance _________________
Based on these results would you say that spousal relationship quality influences cardiovascular
risk? Why or why not?
2 . A t = 2.08 (p<.05) was computed in a study which had 13 participants per group (24 degrees
of freedom). The mean of the first group was 4.68 and the mean of the second group was 2.68.
The estimate of the population standard deviation was 1.00. Compute the effect size. Indicate
whether it is small, medium or large effect size, and report the full results of the t-test analysis.
Answer:
51.84%.
t(24) = 2.08, p < .05, d = 2.00.
Explanation:
The correlation coefficient between spousal relationship quality and cardiovascular risk is -0.72.
The negative sign indicates an inverse relationship between the two variables.
The absolute value of the correlation coefficient indicates a strong relationship between the two variables.
To calculate the percent of variance accounted for by spousal relationship quality:
Square the correlation coefficient to get the coefficient of determination: 0.72^2 = 0.5184.
Multiply by 100 to get the percent: 0.5184 x 100 = 51.84%.
Based on these results, it can be said that there is a strong negative relationship between spousal relationship quality and cardiovascular risk. However, correlation does not necessarily imply causation, so it cannot be definitively stated that spousal relationship quality influences cardiovascular risk.
To compute the effect size:
Calculate Cohen's d: d = (mean1 - mean2) / estimated standard deviation = (4.68 - 2.68) / 1.00 = 2.00.
Determine the magnitude of the effect size using Cohen's criteria: a d of 2.00 is considered a large effect size.
The full results of the t-test analysis are:
t(24) = 2.08, p < .05, d = 2.00.
This indicates that the difference between the two groups is statistically significant and has a large effect size.
