Suppose You Were Interested in Conducting a Study Examining How $\bar{X}$

Short Answer

Suppose you were interested in conducting a study examining how ratings of similarity between oneself and another person were related to how attracted one is to the other person.You conduct this study by giving participants a description of a person named "Sarah." Participants are asked to read the description and then rate on a scale from 1 to 10 how similar Sarah is to themselves.You also ask each participant to rate on a scale from 1 to 20 how likeable they think Sarah is.
X = rating of similarity of target to oneself
Y = rating of likability of the target ("Sarah")
62 people participate in your study,and you obtain the following data: $\bar{X}$ = 6.00
SCP = 66
$\bar{Y}$ = 10.00
SS_X = 40
SS_Y = 136
Calculate the y-intercept for the regression equation for the above data.
