Answer:

Null Hypothesis, $H_0$ : p = 0.27

Alternate Hypothesis, $H_A$ : p > 0.27

Step-by-step explanation:

We are given that the American Academy of Period ontology 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.

<u><em>Let p = % of US adults who admit they lie to their dentist about how often they floss their teeth</em></u>

So, Null Hypothesis, $H_0$ : p = 0.27

Alternate Hypothesis, $H_A$ : p > 0.27

Here, <u>null hypothesis states that</u> the % of US adults who admit that they lie to their dentist about how often they floss their teeth is equal to 27%.

On the other hand, <u>alternate hypothesis states that</u> the % of US adults who admit that they lie to their dentist about how often they floss their teeth seems low and is more than 27%.

Also, the test statistics that would be used for conducting this hypothesis test will be One-sample z proportion statistics.

<h3>What is a right circular cylinder?</h3>

A right circular cylinder is a cylinder that has a closed circular surface having two parallel bases on both the ends and whose elements are perpendicular to its base. It is also called a right cylinder.

Volume of the cylinder = $\pi r^{2}h$
