Final answer:
The question regarding the standard deviation of time for 100 mice cannot be answered with the given information. To compute the standard deviation, we would need the individual times or a measure of the data spread such as variance for the specific sample of mice, and none of the provided data sets pertain to mice.
Step-by-step explanation:
The student's question seems to be about determining which of the given values is closest to the standard deviation of the time required for each of 100 mice. However, there is insufficient information to answer this specific question since the provided data pertains to different scenarios and none of these scenarios include information about the times for the mice.
To calculate the standard deviation of a set of times for 100 mice, we would need the individual time values for each mouse or at least the mean time and some measure that provides information about the spread of the data, such as a range or variance. Once we have the necessary data, calculating the standard deviation involves summing the squared deviations from the mean, dividing by the number of observations to find variance, and taking the square root of the variance to find the standard deviation.
Since the necessary data for the mice example is not provided, we cannot compute the standard deviation for it. The closest we can reference is the standard deviation given as 2.2 minutes for the time needed to complete the short form from the U.S. Census Bureau's study, which is not directly relevant to the question about mice.
