question 87

Short Answer

The number of transistors (in millions) made in a plant in China during the past 5 years follows:
$$\begin{array} { | c | c | } \hline \text { Year } & \text { Transistors } \\\hline 1 & 140 \\\hline 2 & 160 \\\hline 3 & 190 \\\hline 4 & 200 \\\hline 5 & 210 \\\hline\end{array}$$
A) Forecast the number of transistors to be made next year using linear regression.
B) Compute the mean squared error (MSE) using linear regression.
C) Compute the mean absolute percentage error (MAPE).
