50 people are selected randomly from a certain population and just found out 13 people in the sample are over 6 feet tall. What is the point estimate of the proportion of people in the population who are over 6 feet tall?
To calculate the point estimate of the proportion of people in the population who are over 6 feet tall, we can use the formula:
Point Estimate = (Number of Successes) / (Sample Size)
In this case, the number of successes is the number of people in the sample who are over 6 feet tall, which is 13
To calculate the point estimate of the proportion of people in the population who are over 6 feet tall, we can use the formula:
Point Estimate = (Number of Successes) / (Sample Size)
In this case, the number of successes is the number of people in the sample who are over 6 feet tall, which is 13. The sample size is the number of people selected randomly from the population, which is 50.
Using the formula:
Point Estimate = 13 / 50
Dividing 13 by 50, we get:
Point Estimate = 0.26
So, the point estimate of the proportion of people in the population who are over 6 feet tall is 0.26. This means that approximately 26% of the population is estimated to be over 6 feet tall based on this sample.
