Question

The largest commercial fishing enterprise in the southeastern United States is the harvest of shrimp. In a study, researchers monitored variables thought to be related to the abundance of white shrimp. One variable the researchers thought might be related to abundance is the amount of oxygen in the water. The relationship between mean catch per tow of white shrimp and oxygen concentration was described by fitting a regression line using data from ten randomly selected offshore sites. (The "catch" per tow is the number of shrimp caught in a single outing.) Computer output is shown below.

The regression equation is
Mean catch per tow = -5855 + 97.4 O2 Saturation
Predictor Coef SE Coef T P
Constant -5855 2393 -2.45 0.040
O2 Saturation 97.4 34.62 2.81 0.023

 

 

 
c)Construct a 95% confidence interval for ?. (Use a table or technology. Round your answers to three decimal places.)
 
d)What margin of error is associated with the confidence interval in part (c)? (Round your answer to three decimal places.)
