Final answer:

To find the mean and standard deviation for a dataset, input it into a graphing calculator or computer software. Then, calculate the mean and standard deviation. To find a value that is two standard deviations above the mean, multiply the standard deviation by 2 and add it to the mean.

Step-by-step explanation:

To find the mean and standard deviation for a dataset, you can use a graphing calculator or computer software. Let's assume you have the dataset ready. Here are the steps:

  1. Input the dataset into your calculator or software.
  2. Compute the mean of the dataset. This will give you the average value.
  3. Next, calculate the standard deviation. This measures how the data is spread out from the mean. Round the result to one decimal place.

Once you have the mean and standard deviation, 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.
