It is desired to estimate the proportion of motor vehicles registered in a province whose chassis number is incorrectly entered in the traffic document. For this purpose, 135 of the vehicles coming to the inspection station are selected randomly and it is seen that the chassis numbers of 41 of these vehicles are wrongly written on the traffic document.

Five big personality tests are standardized so that the average score is 100 for the entire group of people who take the test each year. However, if we selected a group of 40 people who took the test and computed their average test score, we probably would not get 100. What statistical concept explains the difference between the group mean and the mean for the entire group? Lütfen birini seçin: A. descriptive error B. statistical error C. sampling error D. inferential error
The first blank for both questions is: "estimate of the standard ('distance' or 'score' or 'mean')" Second blanks: "...between a ('sample mean' or 'sample mean difference' or 'score')" Third Blanks: "...and the ('population mean difference' or 'population mean' or sample mean')" The choices are the same for the corresponding blanks, first, second and third.
