A random sample of 300 balls hit into play in college baseball games is taken. For each ball hit into play, it is recorded wheth
er the ball was hit to the left, center, or right of the field, and whether the ball resulted in a hit or an out. Which of the following is the appropriate null hypothesis to test if there is a relationship between the direction of the ball and if it resulted in a hit or an out? (A) H_0H0: The proportion of balls hit to the left, right, and center is the same.
(B) H_0H0: The proportion of balls that result in hits and outs is the same.
(C) H_0H0: The distribution of the direction of the ball is the same for the population of hits and the population of outs.
(D) H_0H0: The direction of the ball and whether it results in a hit or an out are independent.
(E) H_0H0: There is an association between the direction of the ball and whether it results in a hit or an out.
(D) H_0H0: The direction of the ball and whether it results in a hit or an out are independent.
Step-by-step explanation:
Given that
There is 300 balls random sample is taken
We need to find out the appropriate null hypothesis that lies between the ball direction and lead to a hit or an out
So
Based on the given options, the option d is correct as the ball direction and its results either be hit or on out would represent that they are independent
Im not sure but I would seem that the first plan is much better due to the cost. I know this is not an answer but just saying and there just a $0.004 diference wich is practicly the same
