H_a: ? 0

H_o: ? 0

H_a: ? 0

(d) There is a positive linear relationship.

H_o: ? 0

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.

The following quote is from a paper on the weight of the bottle as a possible extrinsic cue with which to estimate the price (and quality) of the wine. The weight of the wine bottles was positively correlated (r = 0.16) with the price of the wines. (a) Does the value of the correlation coefficient indicate that the relationship is weak, moderate, or strong? weakmoderate strong (b) What is the value of r2? Write a sentence that gives an interpretation of this value. (Round the first part to 4 decimal places, and the second part to 2 decimal places). The value of r2 = . Approximately % of the variation in price of the wine can be explained by the linear relationship between price and weight of the wine bottles.
A study was done to look at the relationship between number of movies people watch at the theater each year and the number of books that they read each year. The results of the survey are shown below. Movies 10 4 10 4 0 2 10 7 5 7 8 8 Books 4 8 9 10 16 15 7 7 9 6 5 9 Find the correlation coefficient: r=r= Round to 2 decimal places. The null and alternative hypotheses for correlation are:H0:H0: ? ρ r μ == 0 H1:H1: ? μ ρ r ≠≠ 0 The p-value is: Round to 4 decimal places. Use a level of significance of α=0.05α=0.05 to state the conclusion of the hypothesis test in the context of the study. There is statistically insignificant evidence to conclude that there is a correlation between the number of movies watched per year and the number of books read per year. Thus, the use of the regression line is not appropriate. There is statistically significant evidence to conclude that a person who watches fewer movies will read fewer books than a person who watches fewer…

Imagine that a professor of sociology has two teaching assistants (TAS) who will help him grade assignments for the duration of the semester. The professor wants to make sure that he and the TAS are well calibrated with one another, so he has all three of them grade the first assignment independently. Because the professor grades every assignment on a curve, he first converts the students' scores to z-scores for each grader. The following table shows the z-scores for a population of 10 students in his class for each grader. Student 1 Student 2 Student 3 Student 4 Student 5 Student 6 Student 7 Student 8 Student 9 Student 10 Professor Teaching Assistant #1 Teaching Assistant #2 0.70 0.83 -0.98 2.21 -0.54 0.43 -1.03 -0.01 -0.54 -1.07 1.27 -0.64 0.38 0.80 -1.34 0.10 -2.09 0.85 0.48 0.20 1.27 -1.55 -0.14 0.92 -1.06 0.30 -1.50 1.14 0.57 0.04 The professor is going to use the z-scores to calculate the correlation coefficient between his scores and those of his TAS.
