We wish to estimate what percent of people in the US put the cap back on the toothpaste tube after brushing their teeth. Out of 160 adults sampled, 79 put the cap back on the toothpaste tube after brushing their teeth. Based on this, construct a 95% confidence interval for the proportion, p, of adults who put the cap back on the toothpaste tube after brushing their teeth. $\displaystyle {\left({z}_{{\alpha/{2}}}={z}_{{0.025}}\approx{1.95996}\right)}$.

Apply the Central Limit Theorem or StatKey simulation.

State your values as decimals to three places.

1. < p <
2. Interpret the confidence interval:
