rade = 94 – 6.2 * Hours_Spent_Studying + error What is your takeaway from this regression? Group of answer choices a) Studying is bad, and causes worse grades. b) Students don’t know how to study very well. c) A few outliers are skewing the results. d) Students who are less confident study more, but still do worse. There is an omitted variable skewing the results.

What is Regression Analysis?

a tab = The table below gives the number of hours spent unsupervised each day as well as the overall grade averages for seven randomly selected middle school students. Using this data, consider the equation of the regression line, bo + bx, for predicting the overall grade average for a middle school student based on the number of hours spent unsupervised each day. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, In practice, It would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant. Answer How to enter your answer (opens in new window) esc Step 3 of 6: Substitute the values you found in steps 1 and 2 into the equation for the regression line to find the estimated linear model. According to this model, if the value of the independent variable is increased by one unit, then find the change in the dependent variable . Google Play Store alt 1…
