Fifty people are selected randomly from a certain population and it is found that 12 people in the sample are over six feet tall. what is the best point estimate of the proportion of people in the population who are over 6 feet tall?

Point estimate = Observations/Sample size = O/n
In the current scenario,
Observations (O) = 12 people with over 6 feet tall
Sample size (n) = 50 people selected randomly

Therefore,
Point estimate proportion of people over 6 feet tall =  12/50 = 0.24 or 24%
