Question

In a recent survey of 150 teenagers, 93 stated that they always wear their seat belt when they travel in a car. Assuming the distribution is approximately normal, find the point estimate and standard error for the proportion of teenagers that always wear a seat belt when traveling in a car. Round your answers to two decimal places, as needed.

Answer 1

Point estimate = 0.62

Explanation:

Point estimate = x/n

Given

n is the sample size = 150

X = Those that wear their seat belt

X = 93

Point estimates = 93/150

Point estimates = 0.62
