Answer:
n = 100 scores from a population with σ = 20
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 can be approximated to a normal distribution with mean
and standard deviation, which is also called standard error, of 
n = 5 scores from a population with σ = 20

n = 5 scores from a population with σ = 80

n = 100 scores from a population with σ = 20
.
This one is the correct answer.
n = 100 scores from a population with σ = 40
.
From the given points on the graph we can find which function represents this graph.
A point on the graph is (3, 1). This means if we substitute x = 3 the answer must be 1.
The property of log is that

This suggests, if the base of log is equal to the number for which we are finding the log, the answer must be 1.
So, in this case we have:

Since the answer is 1, the base of log must be 3.
In the given options, only option 3rd is with base 3.
So, the correct answer is option 3.
Answer:
$60.80
Step-by-step explanation
20% Of $76=
Find how much a 20% discount is.
0.2 x 76 = 15.2
Then subtract the amount from the original price.
76 - 15.2 = 60.80
