Question

A random sample of 340 people in Chicago showed that 66 listened to WJKT-1450, a radio station in South Chicago Heights. Based on this sample information, what is the point estimate for the proportion of people in Chicago that listen to WJKT-1450? Question 29 options: 1450 340 About 0.194 66

Answer 1

Answer:

Point of estimate of the true Proportion 'p' = 0.1941

Step-by-step explanation:

Explanation:-

Given data a random sample of 340 people in Chicago showed that 66 listened to WJKT-1450, a radio station in South Chicago Heights.

Given sample size 'n'= 340

Point of estimate of the true Proportion P  = $\frac{x}{n}$

Properties of Estimation

An estimator is not expected to estimate the Population parameter without error.

An estimator should be close to the true value of un-known parameter.

Point of estimate of the true Proportion   = $p = \frac{66}{340}= 0.1941$

Conclusion:-

Point of estimate of the true Proportion = 0.1941
