At a large university, 20% of a random sample of male students have an overall grade point average (GPA) of 3.5 or higher. A ran
dom sample of female student records found that 25% had a GPA of 3.5 or higher. The president of the university wants to determine whether there is evidence of a difference in grades between males and females. What would she write as the null and alternative hypotheses for this situation? Answer choices
H0:p1 − p2 = 0 and Ha:p1 − p2 ≠ 0
H0:p1 − p2 = 0 and Ha:p1 − p2 > 0
H0:p1 − p2 = 0 and Ha:p1 − p2 < 0
H0:p1 − p2 > 0 and Ha:p1 − p2 = 0
H0:p1 − p2 > 0 and Ha:p1 − p2 ≠ 0
Null hypothesis would be there not being a difference, so the difference would be 0.
Alternative hypothesis would be that there is a difference. However, the president of the university does not want to determine whether more males than females, or more females than males, get a GPA of 3.5 or higher, so the alternative hypothesis is =/= 0.
A siphon operates whenever the gravity pushing down the larger column allows the weight upon that edge of something like the siphon to decrease.
Whenever fluid grows deeper throughout the pool, pressure upon that contained temperature rises or increases, and perhaps the liquid gets outside the trap's deep midwicket.
