I f alpha increases the power is also increases.

If the alpha level is increased from 0.01 to 0.05, the size of the critical region expands. This means that it becomes more likely to reject the null hypothesis and make a Type I error. Increasing the alpha level makes the test more liberal and increases the chances of detecting a significant result when one may not truly exist.

What are the negative effects of alpha radiation?
Alpha radiation can be harmful if ingested or inhaled, as it can damage cells and DNA, leading to an increased risk of cancer. However, alpha particles can be stopped by a sheet of paper or human skin, so they are not as dangerous as other types of radiation unless the source is inside the body.
Describe what happens to the proton number and the mass number when an alpha particle is emitted by a nucleus?
Proton number is decreased by two while mass number is decreased by four. Since alpha particle is similiar to helium nucleus.
How did Rutherford explain the results of his gold foil experiment?
Rutherford made the following conclusions:Since most of the alpha particles passed straight through the gold foil without any deflection, most of the space within the atoms is empty.Since some of the alpha particles (which are big in size) were deflected by large angles or bounced backwards, they must have approached some positively charged region responsible for the deflection. This positively charged region is now called the nucleus.As very few alpha particles undergone the deflection, it was concluded that the volume occupied by the central region ( nucleus ) is very small.Since alpha particles which are relatively denser, were deflected by the central volume of charge, it shows that almost the complete mass of the atom must be within the central volume.
Medical hazards of breathing alpha radiation?
Breathing in alpha radiation can lead to lung damage, inflammation, and an increased risk of developing lung cancer. Alpha particles are highly ionizing and can cause DNA damage in lung tissue, increasing the likelihood of mutations that may lead to cancer. Protective measures such as respiratory equipment and proper ventilation are essential in environments with potential alpha radiation exposure.
What type of radiation alpha beta or gamma is emitted by thorium-230?

What happens at the alpha kappa alpha rush?
Attend the rush and you will find out.
What is the critical z value of a two-tailed test with alpha 0.005?
-2.58,2.58
What did Rutherford call the region that deflected the alpha particles?
Rutherford called the region in the gold foil experiment that deflected alpha particles the "nucleus." He discovered that the positive charge and most of the mass of an atom were concentrated in this small, dense region.
How do you perform a Statistical Hypothesis Testing?
To start with you select your hypothesis and its opposite: the null and alternative hypotheses. You select a confidence level (alpha %), which is the probability that your testing procedure rejects the null hypothesis when, if fact, it is true.Next you select a test statistic and calculate its probability distribution under the two hypotheses. You then find the possible values of the test statistic which, if the null hypothesis were true, would only occur alpha % of the times. This is called the critical region.Carry out the trial and collect data. Calculate the value of the test statistic. If it lies in the critical region then you reject the null hypothesis and go with the alternative hypothesis. If the test statistic does not lie in the critical region then you have no evidence to reject the null hypothesis.
What happens when plutonium is frozed?
Plutonium is a radioactive metal that remains solid at extremely low temperatures. Freezing it would not significantly alter its properties or radioactivity. However, proper handling is necessary to prevent contamination and exposure to radiation.
What happens when beta decay occurs?
Alpha rot follows.
What has the author Barbara Allen Pattee written?
Barbara Allen Pattee has written: 'Correlation of increased alpha wave index with increased theta wave index'
What type of damage can alpha particles do to the body?
If Alpha Particles are inhaled, ingested (swallowed), or absorbed into the blood stream, alpha radiation is exposed to sensitive living tissue. The biological damage results in the increased chances of cancer, particularly lung cancer which is caused when alpha emitters are inhaled.
Is the nucleus a very small region of the atom?
Yes. It was shown by Rutherford's alpha scattering experiment.
What happens when uranium gives off an alpha particle?
An isotope of thorium is obtained.
What happens at the end of Alpha and Omega?
at the end they howl at the full moon to say that they are married
