Problem $3,$ Two$-$minute offense: You are provided data containing relationship between Temperature

$(\backslash$deg F$)$ and Resistance $(\backslash$Omega $)$ for a NTC $($remember what NTC stands for?$)$ thermistor that you would like to

use in a new line of refrigerators your company is designing. This line of refrigerators will, of course be

an IoT $($Internet of Things$)$ in that it will notify the user on his$/$her cell phone if the temperature of the

freezer rises above $15\backslash$deg F $($typically freezers should be in the range of $-3\backslash$deg F $-0\backslash$deg F$),$ indicating some type of

malfunction.
