A study was conducted to determine if there was a linear relationship between a person's age and his/her peak heart rate. Give a brief explanation of the type of relationship.

Strong negative linear association (r=-0.968) without outliers

Strong positive linear association (r=0.968) without outliers.

Weak positive linear association (r=0.484) without outliers

Weak negative linear association (r=-0.484) without outliers

What does the square of the correlation (r 2 ) measure?

The percent of variation of the y variable as explained by the LSRL.

How close the points cluster around a linear pattern.

The relationship between the explanatory and response variable.

The residual affect from the LSRL as compared to it's correlation.

A researcher finds that the correlation between the personality traits “greed” and “superciliousness” is -0.40. What percentage of the variation in greed can be explained by the relationship with superciliousness?

Not enough information is given.

The production of American agriculture has grown rapidly due to improved technology (crop varieties, fertilizers, mechanization). Here are data on the output per hour of labor on American farms. The variable is an “index number” that gives productivity a percent of the 1967 level. After creating LSRL for the data, what comments can be made with making a prediction for the year 2025?

There is always a danger whenever we extrapolate beyond the data. In this scenario, we are extrapolating 40 years beyond the data, which may result in an unrealistic prediction.

No comments are needed, making a prediction using the data is the purpose of creating a LSRL.

Making a prediction using the LSRL is perfectly fine, as long as you verify the credibility of the LSRL by using the residual plot.

This particular data requires an exponential regression equation. Therefore, predicting 40 years beyond the data is perfectly fine.

The standard error of estimate is the square root of the unexplained variation.

The answer to this question is beyond the parameters of my intellectual understanding.

If I change the units on each one of my original data points from yards to meters, then my correlation will change as well.

Correlation does not imply causation.

There is an explanatory response relationship with yards to meters.

Only one of the following statements is plausible. Which one?

We found the correlation between Verbal SAT and Math SAT scores to be r = 0.88.

There is a high correlation between the gender of American workers and their income.

We found a high correlation (r = 1.09) between students’ ratings of faculty teaching and ratings made by other faculty members.

The correlation between planting rate and yield of corn was found to be r = 0.23 bushels.

A psychologist wants to determine if there is a linear relationship between the number of hours a person goes without sleep and the number of mistakes he/she makes on a simple test. The following data is recorded. What is the sum of the residuals?

None of the options are available.

The table shown is comparing a person's foot length to their height in cm. Calculate a line of best fit.

f(x) = 25.05x + 5.57

f(x) = 5.57x + 25.05

f(x) = -5.57x + 25.05
