The table below shows the number C of Crayola colors available t years after 1900.
t = years since 1900
3 49 58 72 90 98 103
C = number of colors
8 48 64 72 80 120 120
(a) Find the equation of the regression line for C as a function of t. (Round regression line parameters to two decimal places.)
C(t)=
(b) How many Crayola colors does the regression line indicate for 1993? (Round your answer to the nearest whole number. Note that the actual number is 96.)
