In the 4x100 medley relay event in swimming, four swimmers swim 100 yards, each using a different stroke. The four medley relay swimmers for a college team preparing for their conference championships have the following summary statistics (in seconds) for the four strokes:
1(backstroke) - Expected Value = 49 ; Stand. Dev = 0.34
2(breaststroke) - Expected Value = 54.76 ; Stand. Dev = 0.34
3(butterfly) - Expected Value = 48.5 ; Stand. Dev. = 0.21
4(freestyle - Expected Value = 45.28 ; Stand. Dev. 0.28
Let the random variable T denote the relay team's total time in the medley event. Determine the standard deviation SD(T) (use 3 decimal places).
Please show work on how to get variance.

You are writing a small program that records a swimmers swim
time for a 100 Free Style event, compares it to the best time, and
displays back if swimmer improved or added time. The swim time is
entered in seconds. Prompt user to enter their best time before an
event and current swim time and then display message if user
improved or added time and by how many seconds. It's c++ program
and use iostream header.

To investigate the fluid mechanics of swimming, twenty swimmers
each swam a specified distance in a water-filled pool and in a pool
where the water was thickened with food grade guar gum to create a
syrup-like consistency. Velocity, in meters per second, was
recorded and the results are given in the table below.
