The librarian at a local school collected data on the number of students using the library after school each week during the first 22 weeks of school. The librarian counted the number of students in the library each day and then calculated the total for each week. The weekly totals were plotted in a graph and then a trend line was fit to the data. Students in the Library 600 500 400 300 200 100 5 10 15 20 25 Week Number For which week does the trend line underpredict the number of students using the library by the greatest amount?

Consider the following image of the data. Is the linear trend line a reasonable fit to the data points? Is it linear? +H R²=0.9467 No. The dashed line is well outside many of the error bars. No. The R^2 value is less than 1. Yes. The R^2 value is approximately 1. Yes. The data points have error bars and the line goes through them.
Battery life has a strong, negative, linear relationship with temperature. If the least-squares regredsion line using x = temperature explains 90% of the variation in battery life, what is the correlation, r, between battery life and temperature.
Duration is what typye of data?
find the (a) explained variation, (b) unexplained variation, and (c) indicated prediction interval. In each case, there is sujficient evidence to support a claim of a linear correlation, so it is reasonable to use the regression equation when making predictions. Altitude and Temperature Listed below are altitudes (thousands of feet) and outside air temperatures (°F) recorded by the author during Delta Flight 1053 from New Orleans to Atlanta. For the prediction interval, use a 95% confidence level with the altitude of 6327 ft (or 6.327 thousand feet).
