(10 pts) You are an analyst at MLB.com who was asked to determine how the temperature during a home game inuences attendance. You select a sample of 50 observations of home- game attendance and the day's temperature from around the league, and attempt to estimate the following PRF Y; Zo'i'lXi'i'Ei where Y; is the attendance of each home game and X.- is the temperature at the start of each home game in degrees. Estimate the above PRF using the sample provided. (a) Determine b0 and b1, and interpret them (mind the units of the variables). (b) Determine the coeicient of determination (R2), and interpret it. (c) Using only your regression output, can you say there is a statistically signicant rela- tionship between temperature and attendance at baseball games? Explain your answer. (d) Predict the attendance at a baseball game on an 80 degree day. (DO NOT provide a condence interval around this point estimate). (6) Is there evidence that one additional degree in temperature results in less than 100 additional attendees at the 95% condence level? Provide the null and alternative hy- potheses, the pvalue associated with this test, and your conclusion
