There appears to be 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 56, 29 and 15, respectively. In a recent promotional campaign, of 348 new applicants, 180 applied for G1, 102 for G2, and 66 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?
