Which of the following statistical tests should you use to answer this question: What is the relationship between different levels of blood glucose (in micro grams per millimeter) and diabetes diagnosis (dichotomous variable)?        Linear regression     Correlation      Logistic regression     Neither

Average Age and Length of Service The data show the average ages and lengths of service in months. Age 24.9 25.5 26.1 26.8 26.8 Time 66.7 69.7 73.3 89 82.5 Send data to Excel The correlation coefficient for the data is r=0.932 and α=0.05. Should regression analysis be done? The regression analysis should not be done. O The regression analysis should be done. Find the equation of the regression line. Round the coefficients to at least three decimal places. y' = a + bx a = b = If a service person is 26.6 years old, predict the time that the person will serve. Round the answer to at least one decimal place. The service person will serve months. X

hey could any help me with this question please

Carbon dioxide is produced by burning fossil fuels such as oil and natural gas, and has been connected to global warming. The following output presents the average amounts (in metric tons) of carbon dioxide emissions for the years 1999-2006 per person in the United States and per person in the rest of the world in an effort to determine if non-US per person emissions can help predict US per person emissions.
