1. Two random samples of students are chosen, one from those taking an AP Statistics class and one from those not. The following back-to-back stemplots compare the GPAs. AP Statistics | | No AP Statistics --- |---| --- | 1 | 89 97653 | 2 | 015688 98775332110 | 3 | 133344777888 1100 | 4 | Key: 1 | 8 means 1.8 Which of the following is true about the ranges and standard deviations? A. The first set has both a greater range and a greater standard deviation. B. The first set has a greater range, while the second has a greater standard deviation. C. The first set has a greater standard deviation, while the second has a greater range. D. The second set has both a greater range and a greater standard deviation. E. The two sets have equal ranges and equal standard deviations.

All possible samples of size 20 are taken from a population and the mean is computed for each sample. The mean of the sample means a) is equal to the square root of the sample variance. b) is less than the population mean c) is equal to the population mean d) can be any number Which of the following pairs of parameters is sufficient to define a specific normal curve? a) The mean and the standard deviation. b) The range and the standard deviation. c) The mean and the z-score. d) None of the above. Assume scores on a recent national statistics exam were normally distributed with a mean of 74 and a standard deviation of 6. a) Find the probability that a randomly selected student score more than 77 points? b) A random sample of 50 statistics students is selected. What is the probability that the mean score of this sample is more than 77 points? A sample of size 42 will be drawn from a population with mean 52 and standard deviation 9. a) Why is it appropriate to use the normal distribution to find probabilities for x (sample means)? b) Find the 55th percentile of x.
