Suppose finishing times, in minutes, for running marathons have an unknown distribution with mean 254 and standard = deviation 34 minutes. A sample of size n 58 is randomly taken from the population and the sum of the values is taken. Using the Central Limit Theorem for Sums, what is the standard deviation for the sample sum distribution? Select the correct answer below:
O 4.46 207.15
O 258.94
O 310.72
O 388.40
O 1070.00
