A researcher claims that the stomachs of blue crabs from Location A contain more fish than the stomachs of blue crabs from Location B. The stomach contents of a sample of 16 blue crabs from Location A contain a mean of 198 milligrams of fish and a standard deviation of 36 milligrams. The stomach contents of a sample of 7 blue crabs from Location B contain a mean of 188 milligrams of fish and a standard deviation of 41 milligrams. At alphaequals0.10, can you support the researcher's claim? Assume the population variances are equal. Complete parts (a) through (d) below. (a) Identify the null and alternative hypotheses.
