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 = [tex]\frac{x}{n}[/tex]
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 = [tex]p = \frac{66}{340}= 0.1941[/tex]
Conclusion:-
Point of estimate of the true Proportion = 0.1941
