Question

Suppose the table below gives the number of transistors in computer chips since 1985. Complete parts a and b. Years (since 1985) Transistors (in millions 12 74 328 85 16 .238 15 3.5 a. To fit the data to a function of the form y= abt where t is the number of years since 1985 and y s the number o and s-Inb to form w st. Using linear regression, find values for r and s that will fit the data above. transistors millions take the natural logarithm of both sides ofthe equation to get ln y = In a+1 In b. Then I t = In y In a (Round to four decimal places as needed.)
