Answer:
We want to reduce type II error we carry out the test using a larger significance level (such as 0.10) and not a small significance level α (such as 0.01).
Step-by-step explanation:
Type I error
- Rejecting the null hypothesis when it is in fact true is called a Type I error.
- It is denoted by alpha, α that is the significance level.
- Lower values of alpha make it harder to reject the null hypothesis, so choosing lower values for alpha can reduce the probability of a Type I error.
It is given that the consequences of a Type I error are not very serious, but there are serious consequences associated with making a Type II error.
Type II error
- This is the error when we fail to reject a false null hypothesis or accept a null hypothesis when it is true.
- Higher values of alpha makes it easier to reject the null hypothesis.
- So choosing higher values for alpha can reduce the probability of a type II error.
- The consequence here is that if the null hypothesis is true, increasing the value of alpha makes it more likely that we make a Type I error.
Since, we want to reduce type II error we carry out the test using a larger significance level (such as 0.10) and not a small significance level α (such as 0.01).
This will increase type I error but that is okay since we do not have serious consequences for it.
Just go to math papa. It solves all kinds of problems like these. Anyways the answer is a=4. Please give me a thanks.
