Because it has no units, you can use the coefficient of variation to compare data with different units. Find the coefficient of variation for each sample data set. What can you conclude? CV = - Standard deviation . 100% Mean 1 Click the icon to view the data sets. CV heights = % (Round to the nearest tenth as needed.) CVweights = % (Round to the nearest tenth as needed.) What can you conclude? O A. Height is more variable than weight. O B. Weight is more variable than height. 1: Data Table Heights | Weights 70 167 70 228 77 176 70 174 75 186 72 217 77 171 70 169 76 213 79 191 80 222 74 223 K6/7/22, 11:21 PM Sec. 2.4 Personalized-Eugene Swinger Instructor: Michael Minic Student: Eugene Swinger Assignment: Sec. 2.4 Personalized Date: 06/07/22 Course: 2022 Summer -- Math 1530, Introductory Statistics -- Minic 3. The mean value of land and buildings per acre from a sample of farms is $1300, with a standard deviation of $200. The data set has a bell-shaped distribution. Assume the number of farms in the sample is 77. (a) Use the empirical rule to estimate the number of farms whose land and building values per acre are between $1100 and $1500. farms (Round to the nearest whole number as needed.) (b) If 25 additional farms were sampled, about how many of these additional farms would you expect to have land and building values between $1100 per acre and $1500 per acre? farms out of 25 (Round to the nearest whole number as needed.)
