A dotplot of the distribution of height for Mrs. Navard’s class is shown, along with some numerical summaries of the data. Suppo
se that Mrs. Navard has the entire class stand on a 6-inch high platform and then asks the students to measure the distance from the top of their heads to the ground.
What are the standard deviation and IQR of the new distribution of distance?
1. SD = 4.29, IQR = 13
2. SD = 10.29, IQR = 13
3. SD = 4.29, IQR = 7
4. SD = 10.29, IQR = 7
5. SD = 7.29, IQR = 10
