PLEASE SHARE YOUR EXCEL SCREENSHOTS OR FILES WTH ME Using the data below, which represent the measured temperatures of a metal rod under varying heat inputs,

perform the following tasks:

a$)$ a$)$ Calculate the least$-$squares estimates of the thermal response constant and the initial temperature

of the metal rod.

b$)$ b$)$ Write the equation of the least$-$squares line. $($Note: Provide detailed hand calculations and

compare with the Excel results.$)$

c$)$ c$)$ Compute the coefficient of determination $($R$^(2)).($Note: Provide a graph to be plotted only by Excel.$)$
