Ascientist conducts a study to determine the effects of the mineral cadmium on the weight of mice. she adds 5 mcg of the mineral to the daily diet of 100 4-week-old laboratory mice. every week, the researcher records the weight of each mouse. at the end of the study, the scientist notes that 3 mice died, 40 mice lost weight, 40 mice gained weight, and the remaining 17 mice didn't gain or lose weight during the 12-week period. based on this information, what would you tell the researcher about her findings?

The findings are not meaningful because of the way the scientist designed her study

Explanation:

The researcher added 5 mcg of cadmium to the daily diet of rats, ie every day the rats ingested 5 mcg cadmium, so the researcher should record the weight of the rats daily, as the daily intake of mineral could influence daily in the body. of the animals. However, the researcher weighed the mice once a week, showing that the evaluation of the results may have been poorly designed. In addition, the research results were totally uneven for a study where all mice received the same treatment.

From this, we can conclude that the findings are probably not significant because of the way the scientist designed her study.
