Explanation Given info: Plot ten points and add a point on the upper left corner of the plot. Calculation: Applet procedure: Step-by-step applet procedure of the regression is as follows: In statistical applets choose the regression by eye applet . Drag the upper-left corner point out of the axis to remove it. Plot a point by clicking on the blank plot “a circle appears”. Similarly plot ten points “10 circles appears” Drag the green line according to the scattered points. Click on regression a line appears. The applet output is as follows: From the applet output, the regression equation appears by placing the cursor on the red line in the applet is Y = 0

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 p…

In addition to the in-school milk supplement program, the nurse would like to increase the use of daily vitamin supplements for the children by visiting homes and educating about the merits of vitamins. She believes that currently, about 50% of families with school-age children give the children a daily megavitamin. She would like to increase this to 70%. She plans a two-group study, where one group serves as a control and the other group receives her visits. How many families should she expect to visit to have 80% power of detecting this difference? Assume that drop-out rate is 5%.
