Problem 3 , Two - minute offense: You are provided a . csv file containing relationship between Temperature ( F ) and Resistance ( )

Problem 3, Two-minute offense: You are provided a .csv file containing relationship between
Temperature (F) and Resistance () 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 loT (Internet of Things) in that it will notify the user on his/her cell phone if the
temperature of the freezer rises above 15F(typically freezers should be in the range of -3F-0F),
indicating some type of malfunction.
a.(15 pts) Load the .csv file from eCampus and then remember to save it as an .xlsx file (if using Excel).
Plot the data to make sure it looks OK. Create linear regression fit and plot it. Well, that doesn't
work. Looks like we need to go to higher ordered equations.
b.(20 pts) Create a quadratic ) equation fit of the data and plot the equation on the graph
created in (a.). We wish the error in temperature for the range of (-10F-50F) to be 2F. If a
quadratic equation won't meet this specification, continue to increase the power (cubic,4th power, .
..) until it does.
