Bivariate Correlation and Regression A researcher is studying which variables have an effect on the number of face-to-face interactions we have with friends. She hypothesizes that one of the most important variables will be a person’s age; older people may be less likely to use electronic forms of communication, and more likely to see their friends face-to-face. The researcher randomly sampled 6 people, and gathered the following data: Age Number of face-to-face interactions with friends per week 25 14 56 21 31 17 67 28 45 19 65 29 First things first: Identify the Independent and Dependent Variables: IV = DV = Now, visualize the data. Draw a scatterplot of these data below, making sure to label the axes. Calculating the regression equation: Find the means of the two variables: Y̅ = X̅ = Step 2: Construct your Computation Table: X (X - X̅) Y (Y - Y̅) (X - X̅)(Y - Y̅) (X - X̅)2 (Y - Y̅)2…

(Round b, to one decimal place and b, to three decimal places.) (b) Use the results from part (a) to test for a significant relationship between x and y. Use a = 0.05. Find the value of the test statistic. (Round your answer to two decimal places.) F = Find the p-value. (Round your answer to three decimal places.) p-value = Is the relationship between x and y significant? O Yes, the relationship is significant. O No, the relationship is not significant.

KidsFeet Regression Line y-Intercept The KidsFeet dataframe contains data collected on 39 fourth grade students in Ann Arbor, MI, in October 1997. Two of the measurements taken on the children were the length in centimeters, (length), and width in centimeters, (width), of their longest foot. This data could be used to answer the following Research Question: How is the width of a fourth-grade student's foot related to the length? Which of the following is the y-intercept of the regression line? ## ## Simple Linear Regression## ## Correlation coefficient r = 0.6411 ## ## Equation of Regression Line:## ## length = 9.817 + 1.658 * width ## ## Residual Standard Error: s = 1.025 ## R^2 (unadjusted): R^2 = 0.411 ( ) 1.0248 ( ) 1.6576 ( ) 22.8153 ( ) 0.411 ( ) 9.8172 ( )0.6411
