Use the following to answer the questions below:
The owner of a small pet supply store wants to open a second store in another city, but he only wants to do so if more than one-third of the city's households have pets (otherwise there won't be enough business). He selects a random sample of 150 households and finds that 64 have pets.
-Verify that the sample size is large enough to use the normal distribution to construct a confidence interval for the proportion of the city's households that own pets.
