Question

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 17 blue crabs from Location A contain a mean of 199 milligrams of fish and a standard deviation of 39 milligrams. The stomach contents of a sample of 9 blue crabs from Location B contain a mean of 185 milligrams of fish and a standard deviation of 41 milligrams. At a =0.10, 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. Choose the correct answer below.

My answer for letter A is Ho: u1-u2< 0

Ha: u1-u2>0

( B) Find the standardized test statistic for u1-u2.

t= ______ ( Round three decimal places as needed)

(C) Calculate the P- value

P= ______ ( Round to four decimal places as needed)

(D) State the conclusion

Fail to reject or reject

is or is not

Can you please explain to me this math problem and can you break this math problem down for me because I am struck on math problem. If you can show me how to work this math problem. Thank you.

Step 1

In this question, it has been given the data for two samples which has mentioned on whiteboard,

And we have to conduct a hypothesis testing, researcher claims that the stomachs of blue crabs from Location A contain more fish than the stomachs of blue crabs from Location B.

Step 2

Here we have done our calculations for hypothesis testing, ...
