**Transcription of Survey Description for Educational Purposes**

A survey was conducted in the town of Mechanicsville to estimate the proportion of cars that are red. A random sample of 25 cars from a student parking lot at Lee-Davis High School was taken. Which of the following statements is not correct?

(a) This sample may not be representative of the cars in Mechanicsville because mainly students park at Lee-Davis High School.

(b) If the particular parking space is vacant, we can simply select another parking space at random because it is unlikely that a space being vacant is related to the color of the car.

(c) It would be an error to simply select the first 25 parking spaces in the lot closest to the auditorium because there are a number of parking spaces there reserved for Drivers Ed vehicles, whose primary color is white.

(d) A different team doing the sampling independently would likely obtain a different answer for their sample proportion.

(e) The results can be applied to all cars in the city of Mechanicsville.

Expert Solution

Step 1

A random sample is used to provide information about the population and to given a valid inference about the population. The random sample is also known as the probability sample. In this case, the sanple is not selected in a way that each member of the population has sinilar chance of getting selected in thw survey.

As the cars are not selected randomly, i.e., the sample was only selected from the students parking, we cannot apply the results of this study to the all cars of city of Mechanicsville.
