Answer:
There is a significant difference between the means of the two population
Step-by-step explanation:
The mean number of catfish caught daily at Lake Martin is 85, with the number of catfish ranging from 75 to 140.
Range = 140 - 75 = 65
The mean number of catfish caught daily at Smith Lake is 104, with the number of catfish ranging from 96 to 183.
Range = 183 - 96 = 87
Difference in mean = 104 - 85 = 19
If the confidence interval includes 0 we can say that there is no significant difference between the means of the two populations, at a given level of confidence
But by considering the mean difference and the value of range, we can say that
There is significant difference between the means of the two population
I believe that -16 is the answer to the question above.

Answer: 24
Step-by-step explanation:
Given

dividing whole equation by 2, we get

Mean is given by the sum of the value of entities divided by the total no of entities

The answer
1 /3 radius^2 x height 3
Pi/3 *r^2 x 9 3 = 3 pi ^2
r=1, volume = 3 pi
r=2, volume = 12 pi
r=3, volume = 27pi
