t is known that 51% of American college students fail a course during their freshman year. A university journal club randomly samples 9 upperclassmen and asks them if they failed a course during their freshman year, 3 say they have. Suppose a hypothesis test is to be conducted to determine if the proportion of students who failed a course during their freshman year is less than 0.51. The random variable is X = the number of students in the sample that failed a course during their freshman year. What values of X are considered "as or more unusual" than the observed count if the null hypothesis is true? X ≥ 3 3 ≤ X ≤ 4.59 X ≥ 4.59 X ≤ 4.59 X ≤ 3

Question
It is known that 51% of American college students fail a course during their freshman year. A university journal club randomly samples 9 upperclassmen and asks them if they failed a course during their freshman year, 3 say they have. Suppose a hypothesis test is to be conducted to determine if the proportion of students who failed a course during their freshman year is less than 0.51.
The random variable is X = the number of students in the sample that failed a course during their freshman year. What values of X are considered "as or more unusual" than the observed count if the null hypothesis is true?
X ≥ 3
3 ≤ X ≤ 4.59
X ≥ 4.59
X ≤ 4.59
X ≤ 3
