Predictions from a sample of survey respondents are likely to be valid only when the sample is representative of the population as a whole. true or false

Answers

Answer:

Explanation:

A representative sample is a subset of a population that seeks to accurately reflect the characteristics of the larger group. For example, a classroom of 30 students with 15 males and 15 females could generate a representative sample that might include six students: three males and three females.

Answer:

True

Explanation:

Most survey researchers want to use results from a sample to make predictions about a population. For example, in the political candidate survey, researchers might want to predict how all voters feel about the candidate based on results from a sample of voters. Predictions from a sample are likely to be valid only when the sample is representative of the population as a whole (in this case, all voters).

A father has AB blood and his wife has type O blood. What are the possible blood type percentage of their children.​

Answers

Answer:

If a father has a blood type AB and his wife has a blood type O, their children could be a blood type A or B, with a 50/50 chance.

Explanation:

Blood type and heredity are determined by surface antigens on the red blood cell, called A and B. The surface antigens provided by each parent are genetically encoded:

Blood type A corresponds to the presence of antigen A, and its genotypic expression can be A/A or A/O. Blood type B, whose genotype is B/B or B/O, is due to the presence of a gene containing the B antigen. AB blood —due to co-dominance— has a gene for A and another for B, with genotype A/B. Blood type O, characterized by the absence of surface antigens, behaves as a recessive trait, which only manifests itself in the absence of surface antigens A and B. The genotype is O/O.

In the case posed the father has the blood type AB and the mother the blood type O, so:

- ♂ blood type AB, alleles A|B

- ♀ blood type O, alleles O|O

The crossing can be seen graphically in the diagram:

Alleles A B

O A|O B|O

O A|O B|O

According to this, the offspring of this man and his wife could be:

Children with blood type A, genotype A|O, 50% Children with blood type B, genotype B|O, 50%

At 0800 hr a nurse initiates 1, 000 ml intravenou IV infusion on a client, which is running at 125 ml /hr. It is now 1300 hr . How much fluid is left in the IV bag?

Answers

This is actually simpler than it seems.

What you would want to do first is understand military time.

0800 hours is 8am, and every 100 added to this number is equal to one hour, which mean 1300 is equal to 1pm.

That is a 5 hour difference, which means you would want to multiply 125 by 5 since the IV’s infusion is running at 125 ml an hour.

The answer to this is 625 ml used.

We aren’t finished yet though, we need to find how much is left in the IV, so we simply subtract 625 ml to the 1,000 original to the the answer of:

375 mls remaining in the IV bag.

Hope this helps :)))))

The IV bag or intravenous bag is used to administer the fluid intravenously. The amount of fluid present in the IV bag is 625 milliliters.

Given:

Time at which IV starts = 8:00 hr

Rate at which IV is dripping = 125 ml/hr

Final Time given = 13:00 hr

Now,

The drip was initiated at 8:00 a.m., such that:

[tex]\rm Rate &=\rm \dfrac{Volume}{\rm Time}[/tex]

As we know:

Rate = 125 ml/ hr and Time = 13:00 - 8:00 = 5 hrs

Calculating the rate, we get:

[tex]125 &=\dfrac{\rm Volume}{5}[/tex]

[tex]125 \times 5 &= \rm Volume\\\\625 &= \rm Volume[/tex]

Thus, the volume left in the IV bag is 225 ml.

What are the limitations of correlational research?

Answers

Explanation:

Limitations of Correlations

Correlation is not and cannot be taken to imply causation. Even if there is a very strong association between two variables we cannot assume that one causes the other. For example suppose we found a positive correlation between watching violence on T.V. and violent behavior in adolescence.

An important limitation of correlational research designs is that they cannot be used to draw conclusions about the causal relationships among the measured variables. Consider, for instance, a researcher who has hypothesized that viewing violent behavior will cause increased aggressive play in children

Correlational study,  It's impossible to infer causes, and a high correlation between variables might be deceiving.

Correlational research approaches have the drawback of not being able to make conclusions regarding the causal links between the measured variables. Consider the hypothesis of a researcher who claims that youngsters would engage in more aggressive play if they are exposed to violent conduct.
