Question
Test the claim that the proportion of people who own cats is larger than 40% at the 0.01 significance
level.
The null and alternative hypothesis would be:
Ho: µ < 0.4 Họ:p > 0.4 Ho:p< 0.4 Ho: µ > 0.4 Ho:p
H1:µ > 0.4 H1:p < 0.4 H1:p > 0.4 H1: µ < 0.4 H1:p # 0.4 H1:µ # 0.4
= 0.4 Ho:µ = 0.4
The test is:
right-tailed two-tailed left-tailed
Based on a sample of 600 people, 48% owned cats
The test statistic is:
(This is called the Z-Stat in your StatCrunch output.
Round to 2 decimal places.)
The p-value is:
(Round to 2 decimal places.)
Based on this we:
O Fail to reject the null hypothesis
O Reject the null hypothesis
