Explanation Given: The following data are adapted from a report by D. Solomon that relates the number N of persons injured per 100 accident-involved vehicles to the travel speed s in miles per hour. s 20 30 40 50 60 N 25 32 38 43 60 Table ( 1 ) Approach: A function N = N ( t ) is exponential with base a if N changes in constant multiples of a ; that is, if t is increased by 1 , the new value of N is given by multiplying by a To determine (b) To find: The value of N ( 70 ) and its meaning in practical terms. To determine (c) To find: The effect in number of people injured per 100 accident-involved vehicles with an increase in 1 mile per hour of speed.

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…
