Step-by-step explanation:
Range is the set of value that corresponds with the domain
range=2
domain is (-∞,∞) all real numbers
Answer:
By the Central Limit Theorem, the distribution of ¯ x is approximately normal with mean 187 and standard deviation 2.05.
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.
The lengths of adult males' hands are normally distributed with mean 187 mm and standard deviation is 7.1 mm.
This means that
Suppose that 12 individuals are randomly chosen.
This means that
What is the distribution of ¯ x?
By the Central Limit Theorem, the distribution of ¯ x is approximately normal with mean 187 and standard deviation 2.05.
A. 42
JN, which is the whole line, equals 78. We learned that JK, KL, and MN are all equal, and that LM equals three points.
So, there are 6 parts to the line in total. Dividing 78 by 6 gives you 13 for a sixth of the line.
Now, to find LN all you have to do is know that LM is 13 times three. And just add one more 13 from MN.
13 x 4 = 42 as your answer. I hope you were able to follow my explanation lol
