Question

A recent study conducted by the state government attempts to determine whether the voting public supports 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 .66. What is the critical value (given in terms of the value of the test statistic) at α = .10? 1.282 1.645 1.960 2.326

Answer 1

Null hypothesis

Ho p=0.66)

vs

Alternative hypothesis

Hp0.66)

= 0.10)

Z critical value for right tailed test with is =1.282..........by using Z table or Excel command =NORMSINV(1-0.1)

= 0.10)
