It`s already in standard form but anyways the correct answer is 49.08
Answer:
center = 98.6, variability = 0.08
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean
and standard deviation 
The center is the mean.
So 
The standard deviation of the sample of 50 adults is the variability, so

So the correct answer is:
center = 98.6, variability = 0.08
Answer: 490 feet
Step-by-step explanation: Since the game field is 40% longer than the practice field, it is 140% or 1.4 times the practice field. 350•1.4 is 490 feet.
