Question
Please answer each part of the question as completely as possible:
An experiment was conducted at a large seafood company to investigate the effects of storage temperature and type of seafood on bacterial growth on the food. Three storage temperatures were studied (0°C, 5°C, and 10°C). Three constant environment chambers were randomly assigned to operate at one of the three temperatures. Within each storage unit, oysters and mussels were randomly assigned to one of the two shelves in the unit. The seafood was stored at the assigned temperature for 2 weeks. At the end of the two weeks, a bacterial count was obtained from a randomly chosen sample on each shelf. The resulting data are shown below (the numbers under oysters and mussels are log bacterial count/mg) Seafood Type Storage Unit Temperature ("C) Oysters 3.6882 1.8275 5.2327 7.1950 9.3224 7.4195 9.7842 6.4703 9.4442 Mussels 0.3565 1.7023 4.5780 5.0169 7.9519 6.3861 10.1352 5.0482 11.0329 0 4 10 10 10 (2 pts) (6 pts) (2 pts) (5 pts) What is the experimental unit for temperature? Why was it necessary to include nine storage units instead of three? What is the experimental unit for seafood type? State ALL the null and alternative hypotheses?Explanation / Answer
(first part) type of sea food type
(second part) because for each temparature combination we need 9 and here we can find interaction between temperature and storage type
(third part) storage units are the experimental unit for seafoof type
(fourt part)
null hypothesis H0: a.there is no effect of temparature ,b. there is no effect of storage unit
alternate hypothesis Ha. a. at least one temprature is different from another
b. atleast one storage unit is different from another
