Answer:
156,23
Step-by-step explanation:
let the numbers be x and y and x>y
x+y=179
x-y=133
add
2x=312
x=156
156+y=179
y=179-156=23
1. X = 14
2. X = 120
3. X = 9.24
4. X = 16
5. X = 193.6
6. X = 11
7. X = 7.8
8. X = 446.4
9. X = 26.25
10. X = 6.6
11. X = 9
12. X = 2.01
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
.
When you convert feet to inches, every one foot becomes 12 .
You're taking a batch of something out of the original big packages,
and putting the whole thing into new small packages, so of course
you wind up with more packages.
