1 2 3 4 5 TIME REMAININ 58:04 The mean shoe size of the students in a math class is. 7.5. Most of the shoe sizes fall within 1 standard deviation, or between a size 6 and a size 9 . What is the standard deviation of the shoe size data for the math class? 1.5 2.7 3.0 3.8

To find the standard deviation, we can look at the range of shoe sizes that falls within one standard deviation from the mean. Given that the mean is 7.5 and most shoe sizes fall between 6 and 9, we can calculate the standard deviation as follows: The distance from the mean (7.5) to the lower boundary (6) is 1.5, and the distance to the upper boundary (9) is also 1.5. This tells us that 1 standard deviation equals 1.5. Therefore, the standard deviation of the shoe size data for the math class is **1.5**.
