2.1-a is the probability of
type 1 error
type 2 error
The significance level (alpha) is the probability of type I error.
The F distribution is positively skewed with a range from 0 to oo,
1 - 0 to +8
Value of F must be positive or zero, since variance are squares. so its vale lies between 0 to +8
2 - Probability of acceptance region = 1- alpha
Region of acceptance. The region of acceptance is a range of values. If the test statistic falls within the region of acceptance, the null hypothesis is not rejected. The region of acceptance is defined so that the chance of making a Type I error is equal to the significance level.
