Brian and Yolanda want to find the mean weight of cats at their local pet adoption center. So they each randomly select cats at the shelter and measure the weights. The results are shown below (in pounds). Use the data to answer the questions. Brian's sample: 18, 5, 20, 13, 10, 14, 11 Yolanda's sample: 11, 12, 7, 17, 15, 19 (a) What is the sample size for Brian's sample? (b) What is the sample size for Yolanda'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 Brian's sample O Yolanda's sample Why? O It has the smaller mean. O It has the larger mean. O It has the smaller sample size. O It has the larger sample size.
