1. The American Academy of Periodontology released a survey revealing that 27% of US adults admit they lie to their dentist about how often they floss their teeth. Periodontist Dr. Garcia believes that the percentage seems low, so he decides to conduct his own hypothesis test to determine the true proportion. What should he write as the null and alternative hypotheses for this situation? (2 points)

a	H0: p = 0.27; Ha: p > 0.27
b	H0: p = 0.27; Ha: p
c	H0: p = 0.27; Ha: p 0.27
d	H0: = 0.27; Ha: > 0.27
e	H0: = 0.27; Ha:

2. Jerry's Fish Shack claims that 16% of its employees are late to work once a week. The manager surveyed 25 employees and found that actually 20% are late to work once a week. What does the test statistic calculation look like in this situation for an appropriate hypothesis test? (2 points)

O 0.16-0.20 Z= 0.20 ( 0.80 ) 25 O Z = 0.20-0.16 0.20 ( 0.16) 25 O Z = 0.20-0.16 0.20 ( 0.80 ) 25 O Z = 0.20-0.16 0.16 ( 0.84 ) 25 O Z= 0.16-0.20 0.16 ( 0.84 ) 25
