14) Fill in the Blank. You run a regression analysis on a bivariate set of data (n=25). With x(x-bar) -58.2 and "y=42.5 (y- bar), you obtain the regression equation yly-hat) - 3.111x-23.245 with a correlation coefficient of r=-0.095. You want to predict what value (on average) for the response variable will be obtained from a value of 50 as the explanatory variable. What is the best predicted response value, ya = ?

Data analysis in health care today includes two important elements: human and machine. Data analysts serve an important role by interpreting health care data and making recommendations to stakeholders for its potential impacts and uses. These highly-skilled individuals also rely on cutting-edge technology to aid in data collection, analysis, implementation, and assessment. Evaluation Title: Data Analytics Technology Pitch Part I: In one paragraph, discuss the role of data analytics in health care today. Assume the role of a performance improvement...

The table below gives the number of hours five randomly selected students spent studying and their corresponding midterm exam grades. Using this data, consider the equation of the regression line. ☺ = bo + x, for predicting the midterm exam grade that a student will earn based on the number of hours spent studying. Keep in mind, the correlation coefficient may or may not be statistically significant for the...
