Q. A large random sample of American students in seventh grade showed that 20% 20 \% of them were reading below grade level.\newlineBased on this data, which of the following conclusions are valid?\newlineChoose 11 answer:\newline(A) About 20% 20 \% of all American students in seventh grade were reading below grade level.\newline(B) 20% 20 \% of this sample was reading below grade level, but we cannot conclude anything about the population.\newline(C) About 20% 20 \% of all American students were reading below grade level.
  1. Look at data: Look at the data given: 20%20\% of a large random sample of American students in seventh grade were reading below grade level.
  2. Understand random sample: Understand what a random sample represents: It's meant to represent the larger population, so if the sample is large and random, the percentage in the sample should be close to the percentage in the population.
  3. Analyze answer choices: Analyze the answer choices: A suggests that the sample percentage applies to all seventh graders, B suggests that the sample percentage only applies to the sample, and C suggests that the sample percentage applies to all American students, not just seventh graders.
  4. Apply statistics knowledge: Apply knowledge of statistics: Since the sample is large and random, we can infer that the percentage of the sample is likely to reflect the percentage of the population, but we cannot be certain without knowing more about the sampling method and the population size.
  5. Choose valid conclusion: Choose the most statistically valid conclusion: B is the most cautious and correct interpretation of the data, as it acknowledges the sample result without overgeneralizing to the entire population.

Question
Read the following description of a data set.\newlineOn today's episode of Science Time with Rebecca, Rebecca demonstrates that walking speed affects how wet a person will get in the rain. She simulates walking through the rain at various speeds.Rebecca keeps track of her walking speed (in meters per second), xx. Next, she measures how wet she is by taking the difference of her weight before and after walking through the rain (in kilograms), yy.The least squares regression line of this data set is:\newliney=−4.171x+5.013y = -4.171x + 5.013\newlineComplete the following sentence:\newlineThe least squares regression line predicts that a 11 meter per second increase in walking speed will cause a person to soak up ___\_\_\_ fewer kilograms of water.
