Radioactive cesium (cesium-134 and cesium-137) is a waste product of nuclear reactors. A study examined the radioactive cesium tissue concentration of a random sample of 16 Pacific bluefin tuna, Thunnus orientalis, captured off the coast of California four months after the Fukushima nuclear reactor meltdown of 2011. Here are the findings, (the units are in becquerels per kilogram of dry tissue.) (a) Describe the unknown parameter using the context of this study and correct symbol for this parameter.(b) Construct a 99% confidence interval to estimate this parameter.(c) Give a practical interpretation for this confidence interval, using the context of this problem.

Ascientist investigated the effect of cross-fertilization on the heights of plants. In one study, the scientist planted 15 pairs of a species of plant. Each pair consisted of one cross-fertilized plant and one self-fertilized plant grown in the same pot. The accompanying table gives the height differences, in eighths of an inch, for the 15 pairs. Each difference is obtained by subtracting the height of the self-fertilized plant from that of the cross-fertilized plant. Complete parts (a) through (e) below. Click here to view the data.
