Scott and Shen want to find the mean time students in their class spent watching TV last week. So they each randomly select students in their class and ask for the times. The results are shown below (in hours). Use the data to answer the questions. Scott's sample: 11, 8, 12, 5, 17, 14 Shen's sample: 14, 9, 15, 20, 17, 5, 19, 7 (a) What is the sample size for Scott's sample? (b) What is the sample size for Shen's sample? (c) Suppose you had to choose one sample to estimate the mean. Which sample is more likely to give a good estimate of the mean? O Scott's sample O Shen's sample Why? O It has the smaller sample size. O It has the larger sample size. O It has the smaller mean.
