3. A researcher crossed several randomly-chosen pink tree peonies, Paeonia suffruticosa, to test a genetic model of inheritance. She expected to see red:pink: white offspring colors in the ratio of 8:3:1. Below are the observed color proportions of the 42 plants in the study: Observed Proportions of Progeny Colors Red Pink White 0.762 0.1 19 0.119 Conduct a hypothesis test to determine if the observed proportions significantly differ from the expected ratio. Given: critical = 5.99
