Ms. Blankenship’s tenth grade class is studying the impact of photoperiod on plant growth. Her students fill 100 paper cups with potting soil and a single pea seed. Each cup is randomly assigned to one of four growth chambers. Each of the four growth chambers has an identical artificial light source (25 watts) but each has a different light (L) : dark cycle (D). Chamber 1 is set to 24L : 0D. Chamber 2 is set to 16L : 8D....

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) Examine the recorded concentrations from a random sample of tuna. Is it reasonable to use any of the inferential procedures learned in class on this data? Briefly explain. (b) Determine whether the radioactive concentration in 2011...
