A recent study conducted by the state government attempts to determine whether the voting public supports a further increase in cigarette taxes. The opinion poll recently sampled 1500 voting age citizens. 1020 of the sampled citizens were in favor of an increase in cigarette taxes. The state government would like to decide if there is enough evidence to establish whether the proportion of citizens supporting an increase in cigarette taxes is significantly greater than 0.66. At α = 0.10:
Select which null and alternate is correct.
H_0:p≤1200 , H_a:p>1200
H_0:p≤1500 , H_a:p>1500
H_0:p≤0.66 , H_a:p>0.66
H_0:μ<0.66 , H_a:P≥0.66
At α =0.10 what is the "test statistic"?
What is the "critical value"?
What is the conclusion of the hypothesis test and why?
