The z value for a 99.5% confidence interval estimation is

Biology
1 answer:
kompoz [17]3 years ago
3 0

Answer & explanation:

A confidence interval is an estimated range of a parameter of interest. Confidence intervals are used to indicate the reliability of an estimate. For example, a confidence interval can be used to describe how reliable a search result is.  

In other words, a high confidence interval Z value implies that a survey is more likely to indicate the actual values being presented.

In biostatistics, for example, the Z value can be used in calculations to assess the prevalence of a particular disease and the factors associated with it in a population.

The value of Z, however, is not used as a percentage (like the 99.5% addressed in this question) for calculations. A universal table is used to convert Z values and use them in statistical calculations.

Some examples of Z value conversions can be found in the table attached in this question.

What is the difference between fusion and fission reactions? select 2 that apply
Mumz [18]

Answer:

Difference between fusion reaction and fission reaction.

Explanation:

Fission reaction produce energy while fusion reaction absorb energy.This happens because fission reaction deals with the breakdown of one larger nucleus which result in the generation or liberation of energy.Whereas Fusion reaction combines two smaller atomic nuclei,as a result of which it requires energy for the joining of two smaller atomic nuclei into a larger nucleus.

All northern elephant seals come from a very small genetic pool. This is because in the 1890s a large number of them were very q
Mashcka [7]

Answer:

b. the bottleneck effect.

Explanation:

The bottleneck effect occurs when a population's size is reduced for at least one generation. This will result in a very reduced genetic variation, which can lead to further adaptation problems.

The Founder effect has its similarities (in terms of the resulting reduced genetic pool) with the bottleneck effect, BUT it occurs when a new colony is started by a few members of the original population.

The Hardy-Weinberg equilibrium is a principle in population genetics that states that the genetic variation in a population will remain constant from one generation to the next IF certain conditions are present (no migration, aleatory mating, among others), so this is not the answer.

Genetic drift (refers to the change in the frequency of an existing gene variant in a population due to random sampling of organisms, so it is not the answer.

Greg and Shawn are studying for a physical science test. Greg thinks that the kinetic energy of an object depends on the height
damaskus [11]

The answer is B) Neither is completely right. Shawn is partly correct since kinetic energy depends on mass, but Greg is also partly right since it also depends on speed.

Because, kinetic energy depends on speed, and mass.

Potential energy depends on the height and speed of an object.

Which step in the PCR program would you have to change if your fragment would have been 10 times longer and how?
bekas [8.4K]

Answer:

increasing extension time

Explanation:

The Polymerase Chain Reaction is a technique widely used in molecular biology laboratories to amplify target DNA regions. The standard steps of a PCR are as follow 1-denaturation, 2-annealing and 3-elongation/extension. These steps are repeated 15-40 times in order to exponentially amplify the linear DNA fragment. It is well known that longer extension times can be used as a strategy to increase the yield of longer PCR products. This is because the extension time depends on the synthesis rate of the DNA polymerase used in PCR technique and the length of the DNA fragment to be amplified.
