Answer:

1)
\bar x = 6.2, 2)
\bar x = 8.75, 3)
\bar x = 4.5, 4)
p = 40\,\%, 5)
p = 60\,\%, 6)
p = 10\,\%

Explanation:

1) Mean length of all fish in the sample:


\bar x = (12+5+3+5+8+2+10+9+4+4)/(10)


\bar x = 6.2

2) Mean length of adult fish in the sample:


\bar x = (12+5+8+10)/(4)


\bar x = 8.75

3) Mean length of juvenile fish in the sample:


\bar x = (5+3+2+9+4+4)/(6)


\bar x = 4.5

4) Percentage of sample that were adult fish:


p = (4)/(10)* 100\,\%


p = 40\,\%

5) Percentage of sample that were juvenile fish:


p = 100\,\% - 40\,\%


p = 60\,\%

6) Percentage of sample that were juveniles over 8 inches long:


p = (1)/(10)* 100\,\%


p = 10\,\%
