This is a question about Gamma Gamma correlation lab.

What is the difference between a true and a chance coincidence?

what is the minimum radiation dose in mrem which causes rapid human death?

thanx in advance

Expert Solution

The strength of radioactive sources can be measured by different techniques. One of this is time coincidence technique. This method is based on measuring two events occurring in short interval f time. If the pulses produced by two gamma rays emitted from same radioactive nucleus (eg C060) reach the coincidence unit during resolving time an output pulse is registered and true coincidence is then sais to have occurred. Apart from such true coincidence there will be random coincidence occurring due to pulses which are accidentally in coincidence these are called chance coincidence. The effect of such chance coincidences is to be omitted since the source strength is obtained from knowledge of true coincidence only.

If 100 people get a 350 x 10³ mrem sudden dose of radiation then half of them die in 60 days this dose is considered LD 50/60 ie 50% death rate in 60 days. For 10,00,000 mrem dose however a person will be dead in an hour.

What is/are true about the correlation between the two variables? I. It measures the strength of the linear relation between the variables, as seen in the roundness/flatness of the scatterplot between the two variables. II. If the correlation equals 0, then there is no relation between the two variables. III. If the correlation is very high, then there is a strong causal relation between the two variables. a. l only b.

What is the real difference between between correlation and regression analysis? I see that correlation allows us to examine whether two variables exhibit some kind of association with each other. Does correlation mean means that one variable is dependent on another? Is this an example of correlation - Tips are dependent on the actual restaurant bill? Can you give other examples of correlation and regression? Thanks.

Which of the following statements about correlation are true?

4. Correlation basics Which of the following statements about correlation are true? Check all that apply Correlation is a numerical value between 1.1 and 2. The sign of the correlation indicates the strength or consistency of the linear relationship between two variables. A negative correlation means that two variables tend to change in opposite directions The correlation indicates the strength and the direction of the linear relationship between two variables If the correlation between two variables is 0, there is no clear linear relationship between the...
