Step-by-step explanation:
hope it helps law of physics
Because the ratio of acceptance is 9:100, we simply multiply both by 2:
9:100 = 18:100
The chances of her admitting the 18th student is Option B., 100%
It's simple.
First multiply 3 by 4
It equals 12
Then, multiply 12 by 3
It equals 36
The answer is 36 different combinations.
Hope this helps!
Answer:
The standard deviation of the distribution of sample means for samples of size 60 is of 1.2264.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes 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.
Standard deviation is 9.5 for a population.
This means that 
Sample of 60:
This means that
