A recent poll taken by the movie theatre industry shows that $28 \%$ of the population attends a movie in a theater at least once a month. A sample of 300 people shows that only $12 \%$ of people attends a movie in a theater at least once a month. To determine whether this sample supports the population proportion of 0.28 , a simulation of 100 trials is run, each with a sample size of 200 and a point estimate of 0.12 . The minimum sample proportion from the simulation is 0.10 , and the maximum sample proportion from the simulation is 0.28 . What is the margin of error of the population proportion using half the range?
$\pm 0.03$
$\pm 0.05$
$\pm 0.07$
$\pm 0.09

One of the main ways in which early humans protected their limited food resources was by burring them in the ground, which reduced the risk of certain predators finding them and also helped with cooling.
One of the main ways in which early humans protected their limited food resources was by burring them in the ground ;
Early humans protected their food resources through storage methods, food preservation techniques, community cooperation, the development of tools, and by strategically settling in areas to cultivate land. These strategies allowed them to extend their food supplies and build stronger societies. Over time, these practices evolved alongside human civilization, leading to agriculture and more complex social structures.
