. . 34% Done + . .. Do You Have 5 Seconds? 5 SEC Students in a statistics class tried to stop as close to 5 seconds as possible on a stopwatch. The distribution of times for this task was approximately normal, with a mean of 5.02 seconds and a standard deviation (SD) of 0.10 seconds. 1. Label the values that are 1, 2, and 3, standard deviations (SD) away from the mean. OSD -1 SD 1 SD -2 SD 2 SD 3 SD 3 SD 2. What value is 1 SD below mean? 4. 92 What value is 1 SD above mean? 5.12 Estimate the percent of values within 1 SD of the mean: 6%% 3. What value is 2 SD below mean? 4.82_What value is 2 SD above mean? 5.22 Estimate the percent of values within 2 SD of the mean: 95% 4. What value is 3 SD below mean? 4.72 What value is 3 SD above mean? 5.32 Estimate the percent of values within 3 SD of the mean: 99.7% 5. Use the "Normal Distributions" applet at www.statsmedic.com/applets to find: Actual percent of values within 1 SD of the mean: 68.27% Actual percent of values within 2 SD of the mean: 95. 95%% Actual percent of values within 3 SD of the mean: 99.73% What percent of the stopwatch times are less than 4.82 seconds? 50/0 2= 2.5% What proportion of the stopwatch times are between 4.92 and 5.22 seconds? 0. 815. What stopwatch time is at the 84th percentile of the distribution
