Question

Test the claim that the proportion of people who own cats is significantly different than 20% at the 0.02 significance level.

The null and alternative hypothesis would be:

 

H0:p=0.2H0:p=0.2
H1:p≠0.2H1:p≠0.2
H0:μ≤0.2H0:μ≤0.2
H1:μ>0.2H1:μ>0.2
H0:μ=0.2H0:μ=0.2
H1:μ≠0.2H1:μ≠0.2
H0:μ≥0.2H0:μ≥0.2
H1:μ<0.2H1:μ<0.2
H0:p≥0.2H0:p≥0.2
H1:p<0.2H1:p<0.2
H0:p≤0.2H0:p≤0.2
H1:p>0.2H1:p>0.2

Correct



The test is:

 

left-tailed
two-tailed
right-tailed
Correct
