Step-by-step explanation:
Answer:
The standard deviation of the sample mean is 4 minutes
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed 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:
The standard deviation of the population is 32.
Sample of 64.
So

The standard deviation of the sample mean is 4 minutes
Answer:
Number line A.
Step-by-step explanation:
The first number line A, represents x > 7, which the unshaded circle starting from 7 and moving to the right.
Number line B represents x < 7 with the direction being to the left (opposite of A).
Number line C is synonymous with A, however the starting point is shaded which represents x ≥ 7
Number line D also follows up from B with D representing x ≤ 7
Answer:
(f o f^-1 (10)) = 10
Step-by-step explanation:
f ^ -1 = (x + 10)/10
from solving from f(x) = 10x - 10
since 10x - 10 is a one-to-one function it has an inverse
so f o f^-1 (x) = x
(f o f^-1 (10)) = 10
