What else can I help you with?
If a researcher rejects a false null hypothesis she has made what decision?
Correct decision your welcome and yes took me a long time to find it, evn tho is was right in front of my face
True or false A theory is a hypothesis that has been proven true?
false
One is the additive identity true or false?
False.
Some arthropods are vertebrates true or false?
FALSE
Any two rays will form an angle True or false?
False. They might be parallel, for example
If the null hypothesis is true and the researchers do not reject it then a correct decision has been made?
True because the point of the hypothesis test is to figure out the probability of the null hypothesis being true or false. If it is tested and it is true, then you do not reject but you reject it, when it is false.
What is Hypothesis Testing of Beta Value?
Probability of failing to reject a false null hypothesis.
What is Hypothesis Testing of Type II Error?
Failing to reject a false null hypothesis.
When do we reject a hypothesis?
When we've proven that the hypothesis is false !
What is the Probabilities of Beta Value?
In hypothesis testing, this is the probability of failing to reject a false null hypothesis.
What is a Type II Error - a false-negative error?
Falling to reject (accepting) a false null hypothesis.
What is the power of a statistic?
The power of a statistical test is the probability that the test will reject the null hypothesis when it is, in fact, false. Please see the link.
If a test of hypothesis has a type 1 error probability 01?
If the type 1 error has a probability of 01 = 1, then you will always reject the null hypothesis (false positive) - even when the evidence is wholly consistent with the null hypothesis.
Is it true or false that a scientific theory can never be disproven?
Scientific theories can be disproved. This is a key part of the scientific method, creating hypothesis that can be disproved if they are incorrect. However, you can never really prove a hypothesis - you can find evidence that either fits or doesn't fit. If it doesn't fit the hypothesis needs to be revised or thrown out. If the evidence supports the hypothesis, there may be something that you are missing which may reject the hypothesis.
Type 1 error and type 2 error?
In statistics: type 1 error is when you reject the null hypothesis but it is actually true. Type 2 is when you fail to reject the null hypothesis but it is actually false.
