Answer:
There is no statistical evidence to support the claim, at the 1% significance level, that more than 70% of the population supportsthe ban on household aerosols
Step-by-step explanation:
[tex]H_0: p = 0.70\\H_a: p > 0.70[/tex]
(right tailed test for proportion at 1% significance level)
Sample proportion p= [tex]\frac{150}{200} =0.75[/tex]
p difference = -0.05
Std error for p = [tex]\sqrt{\frac{pq}{n} } \\=\sqrt{\frac{0.7*0.3}{200} } \\=0.0324[/tex]
Test statistic z = p diff/std error
= -1.543
p value = 0.0614
since p >0.01 our alpha we accept H0
There is no statistical evidence to support the claim, at the 1% significance level, that more than 70% of the population supportsthe ban on household aerosols
