The Atlantic bluefin tuna is the largest and most endangered of the tuna species. They are found throughout the North Atlantic O
cean and the mean weight is 550 pounds.37 The Center for Biological Diversity is concerned that this species has been overfished and that the mean weight has decreased. Suppose a random sample of 12 Atlantic bluefin tuna was obtained from commercial fishing boats and weighed. The summary statistics were x 5 535.7 and s 5 37.8. Conduct a hypothesis test to determine whether there is any evidence that the mean weight of Atlantic bluefin tuna is less than 550 pounds. Assume the distribution of weight is normal and use a 5 0.05. Write a Solution Trail for this problem.

Answer:
New amount (decrease) = £17253.53
Step-by-step explanation:
<u>Given the following data;</u>
Amount = £19064.67
Percentage = 9.5%
To find the percentage decrease;
Percentage cost = £1811.14
New amount (decrease) = Original amount - percentage cost
Substituting into the equation, we have;
New amount (decrease) = £19064.67 - £1811.14
<em>New amount (decrease) = £17253.53</em>
