RSCH 665 - Assignment 7.2 Chi-Square Goodness-of-Fit Test A researcher has four prototypes (A, B, C, and D) for a small Unmanned Aerial System (UAS) controller and wants to know if there is a statistical difference in these four controllers from a population standpoint. The researcher asks 120 randomly chosen participants to use each controller and record which one they liked the best. The table below represents the recorded number of times each prototype was preferred by the participants. Prototype A Prototype B Prototype C Prototype D 14 34 61 11 Use the five-step hypothesis testing process and run the Chi-Square Goodness-ofFit Test to determine if there is a statistical difference in the four prototypes from a population standpoint.
