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:
1) 5/2 or 2.5
2) 5/2 or 2.5
Step-by-step explanation:
1) 5/2 = 2.5
2) 10/4 = 5/2 = 2.5
Because the hypotenuse of both are the segments of the same line and straight lines have the same gradient for all segments
Answer:
Slope=3/2
Y-intercept=3
