Question

Use two sample (independent) t test on minitab to determine whether the feeding behaviors of catfish are different above and below the bridge. Use the dataset below to answer this. What is the p value for test that you did? Don't forget to think about test assumptions! Answer format = 0.999

Answer 1

Solution:

Here, we have to use two sample t test for the given data. The Minitab output for this test is given below:

The P-value from this output is given as below:

P-value = 0.512

So, this P-value is greater than alpha value 0.05, so we do not reject the null hypothesis.

There is not sufficient evidence to conclude that feeding behaviours of catfish are different above and below the bridge.
