There is a perception that the pandemic has changed the historical proportion of the population who apply for membership to warehouse stores. Pre-pandemic, the percentage for G1, G2, and G3 levels were 55, 31, and 14, respectively. In a recent promotional campaign, of 202 new applicants, 125 applied for G1, 55 for G2, and 22 for G3 levels. Based on the given information, is there sufficient evidence to suggest that the pandemic may have changed the historical proportions? What is the value of the appropriate test statistic?
