Which of the following hypotheses is correct? a. H0: uHall - uNonHall = 0, H1: uHall - uNonHall =/ 0 b. H0:uD = 0, H1:uD >0 c. H0:uD = 0, H1:uD =/ 0 d. H0: uHall - uNonHall = 0, H1: uHall - uNonHall > 0
It is theorized that hall of fame baseball players live longer due to earning more salary. To test this theory, the Hall of Fame sampled 100 players in the hall and 100 players who did not make it. The players were chosen based on birth year for accurate comparisons and life expectancy was recorded. The data compares as follows:
Hall of Fame Non HOF
75 68
83 72
59 66
Which of the following hypotheses is correct?
a. H0: uHall - uNonHall = 0, H1: uHall - uNonHall =/ 0
b. H0:uD = 0, H1:uD >0
c. H0:uD = 0, H1:uD =/ 0
d. H0: uHall - uNonHall = 0, H1: uHall - uNonHall > 0
Here we have to check whether hall of fame baseball players live longer than Non-Hall players due to earning more salary
which means to test the Hypothesis, the claim should be that the life expectancy of hall of fame baseball players should be greater than life expectancy of Non-hall of fame baseball players.
