Answer to above questions

Linear regression is a common Statistical Data Analysis technique. It is used to determine the extent to which there is a linear relationship between a dependent variable and one or more independent variables. It is a model that showcases the relationship between two variables.

    Y=a+bX+

where Y= Dependent Variable

        X = Independent Variable

        a = intercept

        b = slope

       = residual error

so according to question 1 relation will be expressed as

Y =no.of confirmed case ,X= no.of deaths

and relation will be Y= a+bX+

According to question 2 relation will be expressed as

Y= no.of confirmed case ,X = no.of test performed

and relation will be same as above Y= a+bX+

According to question no 3 relation will be expressed as

Y= no.of recoveries ,X= no.of confirmed case

and relation will be expressed as Y= a+bX+

According to question no.4 relation will be expressed as

Y= no.of deaths and X = no.of recoveries

and relation will be expressed as Y= a+bX+

  Discussion 1: Searching for Causes This week examines how to use correlation and simple linear regression to test the relationship of two variables. In both of these tests you can use the data points in a scatterplot to draw a line of best fit; the closer to the line the points are the stronger the association between variables. It is important to recognize, however, that even the strongest correlation cannot prove causation. For this Discussion, review this week’s Learning...
