A scientist is testing a new sweetener on 10 mice. In a period of 3 days, the mice gain the following weights in grams: 6.1, 6, 5.7, 6.2, 5, 5.8, 4.7, 5.8, 6, and 6.1. To compare this experiment to the results of previous tests, the scientist needs to determine the percentage of these gains in weight that is within pm1 standard deviation of the mean of the 10 weights. What is the standard deviation to the nearest 0.01 of these weights
