For the next questions, test the given claim using the P-value method for
hypothesis testing about a mean. Assume that a simple random sample has been
taken, the population standard deviation is not known, and the population is
normally distributed.
The Common Murre population of birds became endangered in California due to an oil
spill. Biologists want to know if their efforts to restore the colony have been successful.
Since the breeding colony of birds is site dependent, the mean number of breeding pairs
of Common Murres were observed at a specific rock known to be a breeding site. Test
the claim that the mean number of breeding pairs of the Common Murre is greater than
400. Use a .05 significance level and the following raw data collected from seven days
of observations:
-State a conclusion about the null hypothesis and a final conclusion that addresses the original claim.
