Need ASAP will venmo you 10 bucks if it is finished within a hour and has atleast a little work shown thank you
Robin travels rough several intersections with stoplights on her daily drive to work. For 20 days, she
records the number of green lights she encounters and her total commute time in minutes). The
correlation between number of green lights and total commute time is r=-0.491. For these 20 days,
her mean total commute time was 59.5 minutes with a standard deviation of 12.5 minutes, and the
mean number of green lights was 11.1 with a standard deviation of 4.7.
4. Find the equation of the least-squares regression line that predicts the total commute time from
the number of green lights.
5.
