Answer the question by performing a hypothesis test using a 0.05 level of significance. State the Hypotheses and your conclusion using the z-value and p-value.

Answer #1

A recent survey stated that 37% of pet owners talk to their pets
on the telephone. A veterinarian believes that the proportion
should be lower than the survey's claim. In a random sample of 180
pet owners, 33.9% of them said they spoke to their pets on the
telephone. Find the following while performing a hypothesis test to
see if there is sufficient evidence that the proportion of pet
owners that talk to their pets on the telephone is lower...

Test the claim that the proportion of people who own cats is
significantly different than 20% at the 0.01 significance
level.
The alternative hypothesis would be:
μ>0.2
p≠0.2
μ≠0.2
p>0.2
p<0.2
μ<0.2
The test is:
right-tailed
two-tailed
left-tailed
Based on a sample of 500 people, 16% owned cats
The test statistic is: (to 2 decimals)
The p-value is: (to 2 decimals)
Based on this we:
Reject the null hypothesis
Fail to reject the null hypothesis
The conclusion is:
At the...

spoke to their pet on the phone. Does this vet have the right to be
skeptical? Perform the appropriate hypothesis test using a 5%
significance level.
(a) State the null and alternate hypothesis...
