The American Academy of Family Physicians released a survey, revealing that 76% of US adults admit they lie to their doctor about how often they exercise. Dr. Moffett believes the percentage seems high, so she decides to conduct her own hypothesis test to determine the true proportion. What should she write as the null and alternative hypotheses for this situation?

H₀: p=0.76

Ha : p < 0.76

Step-by-step explanation:

A null hypothesis is the common accepted fact that the researcher works to prove it wrong. In this case, the survey revealed that 76% of US adults admit they lie to their doctor about how often they exercise. This forms the null hypothesis.

The alternative hypothesis suggest that a new theory is happening unlike the original one. In this case, Dr. Moffett believes the percentage seems high, so the alternative hypothesis is that the percentage is lower than 76%
