1. Use "2-SampTtest" to work the following problem.
A scientist would like to test the claim that a certain species of fish (species 1) weighs less than
another species of fish (species 2). They test their claim at a 10% significance level.
From species 1, a random sample of 40 fish are examined:
x₁ =
S₁ =
40.5 lbs
1.7 lbs
From species 2, a random sample of 45 fish are examined:
X₂ =
41.2 lbs
S₂ =
2.3 lbs
Ho H1 H2
HAH1<H2
Find the p-value and use the p-value method to test the claim.
Indicate the input (parameter values) required for the "2-SampTtest" calculator function.
p-value =
(round to 3 decimal places)
Decision (circle one): Reject Ho
OR
Don't Reject Ho
Why did you decide the way you did?
Conclusion (statement about the scientist's claim):
