Refer to Exercise 2.CE.5. Suppose you are testing to see if the population proportion of all brides who keep their own name is different from 15%.
a. If testing at a significance level of 5%, would you find evidence for the population proportion of brides between 2001 and 2005 who kept their own names to diff er from 15%? Explain using the p-value you found.
b. If testing at a significance level of 10%, would you find evidence for the population proportion of brides between 2001 and 2005 who kept their own names to diff er from 15%? Explain using the p-value you found.
c. If testing at a significance level of 1%, would you find evidence for the population proportion of brides between 2001 and 2005 who kept their own names to diff er from 15%? Explain using the p-value you found.

In exercise 2.CE.5

What percentage of U.S. brides keep their own names after marriage, as opposed to taking their husband’s name or using some modification (such as hyphenation) of her name and her husband’s? Researchers investigated this question by selecting a sample of wedding announcements in the New York Times newspaper (Kopelman et al., 2009). They found that 18% of a sample of 600 brides sampled between 2001 and 2005 kept their own names.
