1. (20) A research specialist for a large seafood company investigated bacterial growth on oysters and mussels subjected to three different storage temperatures. Nine cold storage units were used. Three storage units were randomly selected to be used for each of the storage temperatures. Oysters and mussels were stored for two weeks in each of the cold storage units. The number of bacteria in each sample was observed. For the "seafood" variable, 1 means oysters and 2 means mussels. storage unit temperature seafood Count 40 1 2 2 6. 3 187 3 97 4 4 1333 151 11186 2841 1668 594 10 17751 10 25215 10 646 8 10 2 156 10 12635 10 2 61877 a.
