Researchers warned to investigate whether there is a relatio

Researchers warned to investigate whether there is a relationship between a subject\'s number of years of education and his or her driving record, recorded as total tickets in a lifetime. What analysis do you suggest the researchers do? What is the null hypothesis? What is the alternative hypothesis? Define the math symbols where necessary. A regression was done for 20 cities with latitude as the explanatory- variable (x) and average January temperature as the response variable (y). The latitude is measured in degrees and average January temperature in degrees Fahrenheit. The latitudes ranged from 26 (Miami) to 47 (Duluth) The regression equation is y = 49.4 - 0 313x, with the following sums of squares: The city Pittsburgh has latitude 40 degrees with average January temperature of 25 degrees Fahrenheit. What is the estimated average January temperature for Pittsburgh, based on the regression equation? What is the residual? What proportion of variation is explained by the linear model?

Solution

3) a) The Researcher needs to collect the data for different people\'s number of years of education, and the his/her driving records,

b) The null hypothesis will be there is a relationship between the two,

while the alternative hypothesis is there is no relationship between the two

We have have to use the chi square test, for this
