Conduct a test for equality of mean catch

Reference no: EM131381140

For given problem, construct a 95% confidence interval for the difference between average catch in the two locations.

Problem :
According to Fortune, there has been an average decrease of 86% in the Atlantic cod catch over the last two decades.

Suppose that two areas are monitored for catch sizes and one of them has a daily average of 1.7 tons and a standard deviation of 0.4 ton, while the other has an average daily catch of 1.5 tons and a standard deviation of 0.7 ton.

Both estimates are obtained from independent random samples of 25 days. Conduct a test for equality of mean catch and report your p-value.
