5.  Is the number of games won by a major league baseball team in a season related to how many runs the team scored for the season?  The table below shows the runs scored (x) and the number of games won (y) for a sample of teams from the 2025 season. X (Runs Scored)    849    798    825    806    793 Y (Number of Games Won)    94    94    93    97    92 Find the equation of the regression line using the least squares approach.  You may use the results of your calculator’s LinReg procedure.

6. Each year seasoned mountaineers as well as many novice climbers looking for a once in a lifetime experience attempt the hardest endurance climb in the lower 48 states.  The glaciated peek of Mt. Rainier, located outside of Seattle Washington, stands at 14,411 feet.  From one of the more popular high camps, Camp Muir at 10,100’, climbers start their 8-12 hour push for the summit in the early morning hours (between 1am and 4am), climbing in the darkness by the light of their headlamps.  A study was conducted to see if the length of time to run 5 miles at sea level could be used to predict the length of time to reach the summit.  A random sample of 17 mountaineers was selected and data on the length of time (in minutes) to run 5 miles (x) and the length of time (in hours) to reach the summit (y) was used to fit a straight-line model.  The results of the simple linear regression are provided below. (b) Calculate b0.  (Round your answer to three decimal places.)
