Answer:
9/11
Step-by-step explanation:
Well we know there are 55 students in total and only 45 of them can either play a string or brass instrument.
So 45/55 is 9/11
Thus probably is 9/11 of a randomly selected student who plays either a string or brass.
Each means to multiply I dont know if thats the word you are asking to us to define
Answer:
The distribution will be approximately normal, with mean 350,000 and standard deviation 25,298.
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.
Population:
Suppose the selling price of homes is skewed right with a mean of 350,000 and a standard deviation of 160000
Sample of 40
Shape approximately normal
Mean 350000
Standard deviation ![s = \frac{160000}{\sqrt{40}} = 25298](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B160000%7D%7B%5Csqrt%7B40%7D%7D%20%3D%2025298)
The distribution will be approximately normal, with mean 350,000 and standard deviation 25,298.
Answer:
A) 10-20
Step-by-step explanation:
Its A because it started with 0 and it went to 10 so it adds 10 each time cause it gave us the hint with 0 to 10,
I hope this helps
