Imagine you are surveying a population of a mountain range where the inhabitants live in the valleys with no inhabitants on the large mountains between. If your sample area is the valleys, and you use this to estimate the population across the entire mountain range, <u>you overestimate the actual population size</u>
<u />
Explanation:
- An estimate that turns out to be incorrect will be an overestimate if the estimate exceeded the actual result, and an underestimate if the estimate fell short of the actual result.
- The mean of the sampling distribution of a statistic is sometimes referred to as the expected value of the statistic. Therefore the sample mean is an unbiased estimate of μ.
- Any given sample mean may underestimate or overestimate μ, but there is no systematic tendency for sample means to either under or overestimate μ.
- Bias is the tendency of a statistic to overestimate or underestimate a parameter. Bias can seep into your results for a slew of reasons including sampling or measurement errors, or unrepresentative samples
After the genetically modified plasmids are inserted into bacteria; the bacteria make proteins from the inserted modified genes.
Explanations;
Plasmids are small, circular strands of DNA that are present in bacterial cells and are capable of self-replication. To add pieces of foreign DNA to bacteria, scientists first package the DNA of interest within the plasmid, and then induce the bacteria to take up the vector. This in turn makes the host bacterium a new, genetically modified organism. Once inside the bacteria, foreign proteins can be made within the bacteria, that is; if the introduced DNA is a gene that encodes a protein, then gene's protein product can be studied by expressing it in the bacteria.
Answer:
where is the statement to answer the question
Based on the observance of DNA, now appearing as 3 segments, the purpose of the enzyme was most likely to split and or break down, cut the DNA at appropriate sites of the respective nucleotide sequences, that the enzyme can recognize and cut, ultimately producing these 3 segments.
D, death & birth rates are at an equilibrium causing population to be constant
