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
.
Answer:
80, 70 and 87
Step-by-step explanation:
-Range is mathematically defined as the difference between the largest and smallest data point in a data set.
-Given the mean=79, median=80 and the range is 17.
#let a be the largest score and b be the smallest score:
The sum of the 3 scores is equivalent to the 237.
#we subtract the given median and equate using range to solve for a and b;
Hence, the test scores are 80, 70 and 87
