In a recent study involving 360 US cities economists ran a regression of rates of COVID 19 infections by cities based on the degree of social distancing in these cities. COVID 19 infections are defined by the number of individuals inflected by COVID19 per hundred thousand residents of each city. Social Distancing is defined by the average distance one person stays away from another person inside and outside their home. Cities where social distancing is not practiced at all, this variable will take the value 0. The technique employed was ordinary least squares. The equation for the estimated COVID 19 regression is given by ý = 0.025- 0.5x. %3D

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.
Question
Transcribed Image Text:Information 1:
In a recent study involving 360 US cities economists ran a regression of rates of COVID 19 infections by
cities based on the degree of social distancing in these cities. COVID 19 infections are defined by the
number of individuals inflected by COVID19 per hundred thousand residents of each city. Social
Distancing is defined by the average distance one person stays away from another person inside and
outside their home. Cities where social distancing is not practiced at all, this variable will take the value
0. The technique employed was ordinary least squares. The equation for the estimated COVID 19
regression is given by
= 0.025-0.5x.
The standard error of the intercept coefficient is given by 0.5 and the standard error of the slope
coefficient is given by 0.025. Suppose you also know that the average city has 300,000 residents, 7
hospitals with about 300 beds. Assume that this regression was done in excel and all the default setting
for regressions such as the value of the level of significance or critical value for hypothesis testing were
followed.
Use Information 1 above to answer the following question. The number of observations used for regression is
and the dependent variable is
O 360, COVID19 Infection Rate
O Less than 360, Social Distancing
O 360, Social Distancing
O Less than 360, COVID19 Infection Rate
