Final answer:
The range is calculated by subtracting the minimum value from the maximum value. The standard deviation measures the spread of data from the mean. To find the value two standard deviations above the mean, multiply the standard deviation by 2 and add it to the mean.
Step-by-step explanation:
The range of a data set is the difference between the maximum value and the minimum value. To calculate the range, subtract the minimum value from the maximum value.
The standard deviation measures how spread out the data is from the mean. To calculate the standard deviation, you can use a calculator or computer software. Step-by-step instructions will depend on the specific calculator or software being used. It's important to note that the standard deviation is not rounded for accuracy.
To find the value that is two standard deviations above the mean, multiply the standard deviation by 2 and add the result to the mean.
