Sorry if this has been posted twice, but we have tried this numerous times and can not work it. Due in the morning. Suppose that a hypothesis test is to be carried out by using á = 0.05. What is the probability of committing a type I error? (Give your answer correct to two decimal places.)
Sorry, but what is a type I error?
occurs if you reject the null hypothesis when it I true
The probability of committing a type I error is the level of significance, α.
See:

We have look at this site and it did not help us at all, with it only giving us the a = 0.05, we do not know how to work it out. There has been 4 of us working on this and no one can get it.
The probability is all the question wanted. If you have a more detailed question, kindly post.
We do not generally follow all your previous posts.
The answer is just what a equals.
To find the probability of committing a Type I error in a hypothesis test, we need to consider the significance level (α).
In this case, α is given as 0.05, which means we have set a threshold of 5% for rejecting the null hypothesis when it is actually true.
The probability of committing a Type I error is equal to the significance level (α), so in this case, the probability of committing a Type I error is 0.05.
Therefore, the probability of committing a Type I error is 0.05 or 5%.
