Answer:
μ= 65 inches; σ= 0.625 inch
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed(bell-shaped) random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem, we have that:
By the central limit theorem, the sample of 16 will have:
So the correct answer is:
μ= 65 inches; σ= 0.625 inch
Answer:
d = 5/6t
Step-by-step explanation:
5 stories every 6 seconds
at 12 seconds, it would have travelled 10 seconds.
using this 2 data in this formula
(y-y1)/(x-x1) = (y2-y1)/(x2-x1)
Note : d = y, t = x;
d1 = 5, t1 = 6, d2 = 10, t2 = 12
we have
(d - 5)/(t-6) = (10-5)/(12-6)
(d - 5)/(t-6) = 5/6
d = 5/6(t-6) + 5
d = 5/6t -5+5
d = 5/6t
(3m - 4n - 7) - (8m + n - 6)
3m - 8m = - 5m
-4n - n = -5n
-7 - (-6) = -7 + 6 = -1
-5m - 5n - 1 is your answer
hope this helps
