Clearly when we add the points given in options to our data we see that the points (7, 73) (7.5, 70) (8.5, 66) are closely related to the data set except (8,35).
Since, the value y=35 is much low as compared to the other data points.
Hence, it will stand out in the plot as compared to other points.
Change the divisor 3.75 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.
