Question 1169410: A hypothesis test is to be performed. State the null and alternative hypotheses.
During the Covid pandemic the proportion of elderly nationwide who have come down with the Covid is 6%. The manufacturer of a Covid vaccine claims that those who get vaccinated are less likely to become ill with Covid.
Select one:
A.
Null hypothesis: proportion of those vaccinated catching the Covid > 6%
Alternative hypothesis: proportion of those vaccinated catching the Covid < 6%
B.
Null hypothesis: proportion of those vaccinated catching the Covid < 6%
Alternative hypothesis: proportion of those vaccinated catching the Covid = 6%
C.
Null hypothesis: proportion of those vaccinated catching the Covid = 6%
Alternative hypothesis: proportion of those vaccinated catching the Covid < 6%
D.
Null hypothesis: proportion of those vaccinated catching the Covid = 6%
Alternative hypothesis: proportion of those vaccinated catching the Covid ≤ 6% Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! I like hypothesis tests to cover the whole spectrum.
Assume the vaccine doesn't work.
Ho: the % is > = 6%
Ha: the % is < 6%
A is the best choice.
