Basic Math

A procurement specialist has purchased 25 resistors from Vendor1 and 35 resistors from Vendor 2. Each resistor’s resistance wasmeasured and reported in Problem 4 spreadsheet of Homework 2.xlsx.You want to compare mean performance. Use R, and draw conclusionswith 0.05 significance. a. First perform the appropriate test todetermine whether to assume equal or unequal dispersions ofresistance for the two vendors. b. Based on your answer in part a,compare mean performance of the vendors with the appropriate ?test.
