- 1What is the critical region?All the test statistics that reject the null hypothesis lie within the critical region
- 2What is the critical value?The test statistic at the limit of the critical region
- 3What is the acceptance region?All test statistics that accept the null hypothesis lie within the acceptance region
- 4How would we know whether H1 is < or > ?If it's decreasing, then <
If it's increasing, then > - 5E.g: X~B(20,0.4) , 10% significance level where H0: p=0.4 , H1: p>0.4 Find critical region and valueUse CD Binomial on calculator
As we get to 11 we find:
P(x≥11) = 1-P(x≤10) = 0.1275
P(x≥12) = 1-P(x≤11) = 0.056
P(x≥11) is above 0.10 while P(x≥12) isn't
Therefore the critical region is x≥12
And the critical value is x=12
