Answer:
Negative 58.73$
Step-by-step explanation:
32-15 = 17
17-7.41 = 9.59
9.59-35.79 = -26.20
-26.20-0.53 = -26.73
-26.73-32 = -58.73

Part A: 5 out 25 lobsters have dangerous levels of mercury
Part B: the 95% confidence interval is given by (4.45, 5.65)
since everything is given all I had to do is find the critical value which can be found from the resource packet = 2.064
Using the formula we find 5.05+-2.064*1.45/5 = ( 4.45,5.65)
For this case, we have 95% of confidence that the true mean for the average number of lobsters with dangerous levels of mercury is between 4.45,5.65
