A study was conducted to determine what proportion of all college students considered themselves as full-time students.  A random sample of 300 college students was selected and 210 of the students responded that they considered themselves full-time students.  A computer program was used to generate the following 95% confidence interval for the population proportion: (0.64814, 0.75186).   Which of the following practical interpretations is correct for this confidence interval?

  1. A) We are 95% confident that the percentage of the 300 students who responded that they considered themselves full-time students was 0.700.
  2. B) We are 95% confident that the percentage of all college students who consider themselves full-time students was 0.700.
  3. C) We are 95% confident that the percentage of the 300 students who responded that they considered themselves full-time students falls between 0.648 and 0.752.
  4. D) We are 95% confident that the percentage of all college students who consider themselves full-time students falls between 0.648 and 0.752.
