The population sizes of many animal species rise and fall over time. Suppose that the population size of a certain species can be modeled by the following function. p(t) = 3350 + 1250 sin 1.5 t. In this equation, p(t) represents the total population size, and t is the time in years. Find the following. If necessary, round to the nearest hundredth.
Period of p:
Frequency of p:
Minimum populations size:
