PLEASE SHARE ME YOUR EXCEL PHOTOS$--$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 $\backslash (\backslash$left$($R$^\{2\}\backslash$right$)\backslash ).($Note: Provide a graph to be plotted only by Excel.$)$
