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 
What is the standard deviation of the distribution of sample means for samples of size 60?
The standard deviation of the distribution of sample means for samples of size 60 is of 1.2264.
I think its b but im not sure
Answer:
Solution given:
y=6/7x+7
Comparing above equation with y=mx+c
we get
m=6/7
a What is the slope of a line parallel to it?
Since for parallel slope are equal ,
slope will be 6/7.
b What is the slope of a line perpendicular to it?
Since for perpendicular line slope is reciprocal to another line but negative so
slope of line is-7/6.
Answer:
B. $10.71
Step-by-step explanation:
15.30 x 0.7 = 10.71
Answer:
A=5/12 B=4/12
Step-by-step explanation:
(1,2,3,4,5)=How many cards are less than 6= 5/12
(3,6,9,12)=How many cards are divisible by 3= 4/12
Hope this helps!
