As the temperature outside decreases, heating bills increases. This implies a ________ correlation between the two variables, with a correlation coefficient value (r - value) between _____ and _____.
Homework Answers
here as both the variables are moving in opposite direction;
As the temperature outside decreases, heating bills increases. This implies a negative correlation between the two variables, with a correlation coefficient value (r - value) between -1 and 0.
Add Answer to:
As the temperature outside decreases, heating bills increases. This implies a ________ correlation between the two...

Now suppose the correlation coefficient for the relationship between a country’s adolescent birth rate (i.e., the rate at which teenage girls give birth) and life expectancy works out to be −0.71. What can we conclude from the value of that correlation coefficient? I. The association between the adolescent birth rate and life expectancy is strong and positive (as the adolescent birth rate increases, life expectancy increases as well). II. The association between the adolescent birth rate and life expectancy is...

If we find that there is a linear correlation between the concentration of carbon dioxide in our atmosphere and the global temperature, does that indicate that changes in the concentration of carbon dioxide cause changes in the global temperature? Choose the correct answer below. O A. No. The presence of a linear correlation between two variables does not imply that one of the variables is the cause of the other variable. OB. Yes. The presence of a linear correlation between...

1-2. The sample of n = 30 people is selected and the sample correlation between two variables is r = 0.468. 1. What is the test statistic value for testing whether the true population correlation coefficient is equal to zero? (calculate t-test statistic) 2. What is the t- critical value for alpha= 0.01. and what you can conclude about population correlation ( is there significant correlation between two variables).

The city's transportation department is interested in studying the relationship between the outside temperature and the number of passengers that ride the main bus line in order to better serve their customers. The manager recorded the temperature at the beginning of the hour and then had a bus driver record the number of passengers that boarded the bus throughout the hour. Calculate the Pearson's correlation coefficient for the dataset below and interpret what that means. temperature passengers 77.1 26 77.1...
