Question

1. (8 points) For the following data items given sample data: 8, 10, 12, 14, 16, 18, 20. Find Mean Median Standard deviation Range Mid Range 2. (2 points) Intelligence quotients (IQs) on the Stanford-Binet intelligence test are normally distributed with a mean of 100 and a standard deviation of 16. Use the 68-95-99.7 Rule to find the percentage of people with IQs between 84 and 116. 3. (2 points) Make sense? Explain your reasoning. "I made a distribution of the heights of the 12 players on our basketball team. Because one player is much taller than the others, the team's median height is greater than its mean height" 4. (4 points) A student scores 70 on an arithmetic test and 66 on a vocabulary test. The scores for both tests are normally distributed. The arithmetic test has a mean of 60 and a standard deviation of 20. The vocabulary test has a mean of 60 and a standard deviation of 2. Find the z-score for each test. Explain how on which test did the student have a better score 5. (2 points) A student scored in the 75th percentile on the SAT. What does that mean? 6. (2 points) True or False. "A score in the 50th percentile on a standardized test score is the median."
