With a sample size of 500 per group and an assumed mortality rate of 25% in the control group and 17.5% in the PCT group there will be 80% probability that a negative result (Confirming the Null Hypothesis) is true. At the same time there will be < 5% probability of falsely declaring...
Acquisition of new skills has the potential to disturb existing network function. To directly assess whether previously acquired cortical function is altered during learning, mice were trained in an abstract task in which selected activity patterns were
A Type I error represents the scenario which occurs when a researcher chooses to make the decision to reject a null hypothesis, when in fact, the null hypothesis is correct and it should have been retained. The Type I error is associated with the alpha level of the stud...
If the null hypothesis is true then it cannot be rejected. True or False? A type I error is: A) always the same as (1 - type II) error. B) the error you make when rejecting the null hypothesis when it is true. C) the error you make when rejecting the alternative hypoth...
tests whether a sample is greater than or less than a certain range of values. It is used innull-hypothesistesting and testing forstatistical significance. If the sample being tested falls into either of the critical areas, the alternative hypothesis is accepted instead of the null hypothesis.1...
