i honestly dont know give me the answer bro
The nurse visits
becase it reduces the percent error and it gives a much better idea of what is the best result
Experimental control is a group of experimental subjects that is not exposed to a chemical or treatment being investigated so that it can be compared with experimental groups that are exposed to the chemical or treatment It is also the standard of comparison. -Also, look for the following things: Experimenter Bias, History, Maturation, Instrumentation, Selection, Order, and Statistical regression. All of these should be questioned.
Force required to move the object forward.
A disclosed observation is when the participants are aware that they are being observed. This reduces ethical issues of consent and privacy but reduces validity due to increased demand characteristics.

Such a mechanism is called a negative feedback.
Increase in variable cost reduces the contribution margin as following formula suggests”Contribution margin = Sales revenue – Variable Cost
combining like terms or subtracting from both sides of the equation.
Correlation determines relationship between two variables. For example changes in one variable influence another variable, we can say that there is a correlation between the two variables. For example, we can say that there exists a correlation between the number of hours spent on reading and preparation and the scores obtained in the examination. One can infer that higher the amount of time spent on preparation may result in better performance in examination leading to higher scores. Hence the above is a case of positive correlation. If an increase in independent variable leads to an increase in dependent variable, it is a case of positive correlation. On the other hand if an increase in independent variable leads to a reduction in dependent variable, it is a case of negative correlation. An example for negative correlation could be the relationship between the age advancement and resistance to diseases. As age advances, resistance to disease reduces.
A large sample reduces the variability of the estimate. The extent to which variability is reduced depends on the quality of the sample, what variable is being estimated and the underlying distribution for that variable.
