Question

A group of scientists were interested in studying the concentrations of radioactive cesium, a waste product of nuclear reactors, in Bq/kg of Pacific tuna off the cost of California, in 2011. This study was prompted by the Fukushima nuclear meltdown, also in 2011.
(a) (2 pts) Examine the recorded concentrations from a random sample of tuna in Q3data.xlsx. Is it reasonable to use any of the inferential procedures learned in class on this data? Briefly explain. (b) (7 pts) Determine whether the radioactive concentration in 2011 is significantly higher that the historical average of 2 Bq/kg.
