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.\n\nthe sample of 40 children is too small to represent all kindergartners.\n\nthe sample was taken at a specific movie, which will skew data towards that type of movie.\n\nthe sample is likely to include a lot more girls than boys, since the movie title is “three pretty princesses.”\n\nthe sample should include the adults with the children instead of only children.\n\nthe sample should include the other peer helpers in her grade to include a greater age range.

Answer

# Brief Explanations: 1. A sample of 40 children might be too small to represent all kindergarten - aged children accurately. 2. Sampling at a specific movie ("Three Pretty Princesses") will likely skew the data towards that type of movie (cartoon/princess - themed). 3. The movie title suggests it may attract more girls than boys, so the sample may not be gender - balanced. The sample is supposed to represent all kindergarteners for movie preference, not adults or peer helpers, so those are not valid criticisms here. # Answer: The sample of 40 children is too small to represent all kindergarteners. 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."
