The expected value of a discrete random variable a. is the most likely or highest probability value for the random variable. b. will always be one of the values x can take on, although it may not be the highest probability value for the random variable. c. is the average value for the random variable over many repeats of the experiment. d. is the value it is expected to assume in the next trial.

The data shown in the table below represents the weight, in pounds, of a little girl, recorded each year on her birthday. age (in years) weight (in pounds) 2 32 6 47 7 51 4 40 5 43 3 38 8 60 1 23 part a: create a scatter plot to represent the data shown above. sketch the line of best fit. label at least three specific points on the graph that the line passes through. also include the correct labels on the x-axis and y-axis. part b: algebraically write the equation of the best fit line in slope-intercept form. include all of your calculations in your final answer. part c: use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.
