A researcher claims that the stomachs of blue crabs fromLocation A contain more fish than the stomachs of blue crabs fromLocation B. The stomach contents of a sample of 16 bluecrabs from Location A contain a mean of 195 milligrams offish and a standard deviation of 38 milligrams. Thestomach contents of a sample of 9blue crabs from Location Bcontain a mean of 188 milligrams of fish and a standarddeviation of 41 milligrams. At α=0.05​, can yousupport the​ researcher's claim? Assume the populationvariances are equal. Complete parts​ (a) through​ (d)below.
A.
H0​:
μ1−μ2<0
Ha​:
μ1−μ2=0
B.
H0​:
μ1−μ2≥0
Ha​:
μ1−μ2<0
C.
H0​:
μ1−μ2≤0
Ha​:
μ1−μ2>0
D.
H0​:
μ1−μ2=0
Ha​:
μ1−μ2≠0
Part 2
​(b) Find the standardized test statistic for
μ1−μ2.
