As the Type II error, β,of a statistical test increases, the power of the test decreases.
As the Type II error, β,of a statistical test increases, the power of the test _____________....
If the type II error rate of a statistical hypothesis test is estimated to be .3, what would the statistical power of the test be? .5 .85 .70 .30
Alpha refers to __________. A Statistical power B The probability of making a Type II error C The probability of making a Type I error D Effect size
If alpha is the probability of committing a Type I error and β is the probability of committing a Type II error in a hypothesis test, the power of the test is given by __________. A. (1 – β) B. β C. alpha D. 1 - alpha)
Question 1 1 pts In classical hypothesis testing, what happens to the probability of Type II Error as we increase the significance level of the test (a)? P(Type II Error) Decreases P(Type II Error) Increases P(Type II Error) Stays the Same
Compute the statistical power Type II error rate 0.25 sample size 100 alpha level 0.01
compute the statistical power: Type II error rate 0.25 sample size 100 and alpha level 0.01
You take a random sample of size 30 and conduct a hypothesis test at the 5 % level of significance . If instead , you take a random sample of size 50 and conduct the same hypothesis test at the same 5 % level of significance , what can you say about the probability of a type I and type II error (all else being equal ) ? A. P (Type I errror ) decreases and P (Type II error...
Explain “Type II Error” (β) in hypothesis testing.
a smaller probability of type II error implies higher power of the test. true or false
___is the probability of a Type II error; and ___ is the probability of correctly rejecting a false null hypothesis. 1-β; β β; 1-β α; β β; α A student hypothesized that girls in his class had the same blood pressure levels as boys. The probability value for his null hypothesis was 0.01. So he concluded that the blood pressures of the girls were the same as boys’. Which kind of mistake did he make? Type I error Type II...
