Empathy means being able to understand what others feel. To see how the brain expresses empathy, researchers recruited 16 couples in theirmidtwenties who were married or had been dating for at least two years. They zapped the man's hand with an electrode while the woman watched, andmeasured the activity in several parts of the woman's brain that would respond to her own pain. Brain activity was recorded as a fraction of the activityobserved when the woman herself was zapped with the electrode. The women also completed a psychological test that measures empathy.Subject1234678910111213141516Empathy ScoreBrain Activity -0.114 0.39 0.019 0.379 0.010.4120.10.5150.153 0.746 0.250.56 0.214 0.717 0.366 0.778375144545667 68 54484768 652862261001.2sub jęct 910.0-20120-8,4Given that the equation for the regression line is ŷ= 0.00683x – 0.03024, what is the residual for subject 9?

Concept explainers

Correlation

Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Linear Correlation

A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.

Regression Analysis

Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.

Suppose you are interested in studying the relationship between the number of visitors a museum gets and the revenue of their gift shop. You take a sample of 27 different days and record the number of visitors and the revenue of the gift shop in dollars. Also suppose on the 27 days you sampled, the number of visitors ranged from 100 people to 600 people. You get the following regression line: ŷ = 5.6x419, where ŷ is the revenue in dollars and x is the number of visitors. We also get that r≈.57. (a) Give the value of the slope of this regression line. Interpret this value in the context of the situation. (b) Is there enough evidence for a correlation? Why or why not? (c) What does our model predict the revenue will be on a day where the museum gets 1000 visitors? Would you trust this prediction? Why or why not?
