Sofia is a helper for the kindergarten class and is in charge of picking a video for their end-of-year party. To choose which type of movie they would like best, she decided to survey every other child entering a matinee for a cartoon called, "Three Pretty Princesses." The total number of children surveyed was 40. What is wrong with the way she selected her sample? Check all that apply. The sample of 40 children is too small to represent all kindergartners. The sample was taken at a specific movie, which will skew data towards that type of movie. The sample is likely to include a lot more girls than boys, since the movie title is "Three Pretty Princesses." The sample should include the adults with the children instead of only children. The sample should include the other peer helpers in her grade to include a greater age range
