If the professor decides to reject the null hypothesis (that means passing the student) when the students get eight or more correct answers, what is the probability of a Type I error?

Use the following information to answer question. A college professor gives a test that has 10 true–false questions. Two students take the test. Student A, who does not know anything about the subject, answers the questions by tossing a coin. The college professor sets up the following hypothesis, where p represents the probability that a student gets an answer right.
H₀: The students do not know anything (p = .5).
H₁: The students know the subject (p > .5).
