Answer:
i think it is B and E
Step-by-step explanation:
Answer:
-3,0,1,2,3
Step-by-step explanation:
Given:
standard deviation = 4.3%
sample size = 15
mean = 26.4%
error = σ/√n
error = 4.3% / √15
error = 4.3% / 3.873
error = 0.0111
0.0111 x 100% = 1.11%
I would say this study is observational-- if it was experimental, they would be doing something with the eels (like feeding them peanut butter to see if it makes them faster, or something like that). I would choose <em>"Observational study, because the divers are not catching eels for a sample."</em>
"27 percent" means 0.27
"of" means "times"
"27 percent of 300" means (0.27 x 300) = 81 .
At the beginning, you asked what percent this is.
81 is 8,100 percent .
