Find the equation of the least squares regression line if: x-bar = 2 sx = 2.3 y-bar = 22 sy = 4.1 r = - 0.94 y-hat = 18.64x + 1.68 y-hat = 25.35 - 1.68x y-hat = 18.64 - 1.68x y-hat = 25.35x - 1.68

The evening newspaper is delivered at a random time between 5: 30 and 6: 30 pm. dinner is at a random time between 6: 00 and 7: 00 pm. each spinner is spun 30 times and the newspaper arrived 19 times before dinner. determine the experimental probability of the newspaper arriving before dinner.
