Hypothesis test
H0=6
H1 not equal 6
n=23
sample mean= 6.05957
s=1.279159803
standard error 0.266723257
level of significance=0.05
test statistic=0.22332
p-value=0.82535 (> level of significance)
Conclusion: Do not reject H0.
*If we conclude that we failed to reject H0, there's possibilities of type II error occurs instead of type I error, am I right?
QUESTION
Calculate the approximate probability of rejecting the null hypothesis if the true mean return were equal to
(a) 6%, (my answer=0, because I have concluded that DO NOT REJECT H0, so should be type II error, not type I error?)
(b) 6.5%. (?)
How do these probabilities relate to the probabilities of the Type I and Type II errors of the test?
