What's the answer to the attached question and why?

A medical study was investigating if getting a flu shot actually reduced the risk of developing the flu. A hypothesis test is performed. Suppose the null hypothesis was rejected with a p-value of 0.0002. The power of the test was 0.90. What type of error could be made and what is the probability of making that error? Choose the correct answer below O A. A Type l error could be made with a probability of 0.0002. O B. A Type ll error could be made with a probability of 0.0002. O c. A Type l error could be made with a probability of 0.90. O D. A Type l error could be made with a probability of 0.10. O E. A Type ll error could be made with a probability of 0. 10.

Explanation / Answer

Solution: A. Type I error could be made with a probability of 0.0002.

Since we have rejected the null hypothesis with a p-value = 0.0002 and we know that type I error is related with rejecting null hypothesis when null hypothesis is true. Therefore we will be making Type I error with a probability 0.0002
