the answer is A
this is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem
Answer: 20 ± 11.32
Explanation: <u>Confidence</u> <u>Interval</u> (CI) is an interval of values where there is a % certainty the true mean value lies in. For example, a 95% CI means there is a 95% certainty the true mean value lies in the interval.
For the data set 2, z-value for 95% confidence interval is z = 1.96
Formula to calculate CI is
x ± 
where
x is mean
z is z-value
s is standard deviation
n is the sample number
Then:
20 ± 
20 ± 
20 ± 
20 ± 11.32
The 95% CI is 20 ± 11.32, which means there is a 95% certainty the true value is between 8.68 and 31.32.
<span>The labs were unable to reproduce the pharmaceutical company’s data
An important characteristic of scientific experiments is that their results can be replicated. In this case, assuming that the laboratories followed the same procedure as the pharmaceutical company, the fact that the data could not be replicated means that the company's claims are invalid. The validity of the claims is more questionable given the huge difference in the final conclusions, with the company reporting a 35% decrease, while the maximum decrease observed by the labs was 8%.
