Answer:
(c) if n is large, then the sampling distribution of the sample mean can be approximated closely by a normal curve.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, the sampling distribution of the sample mean, with a large sample size, can be approximated to a normal distribution with mean
and standard deviation
.
This is valid no matter the shape of the population.
So the correct answer is:
(c) if n is large, then the sampling distribution of the sample mean can be approximated closely by a normal curve.
Length of MN = Length of M′N′ is the correct answer. Hope it helps :))
Answer:
22,36,50,64,78,92
Step-by-step explanation:
The common difference is when you take one term and subtract the previous term from it.
For example, 36-22=14
Hope that helps!

Pipe A filled for 3 days and pipe B filled for 2 days
Both can fill: 1/3 + 1/2 = 2/6 + 3/6 = 5/6
Answer: 5/6 of a day to fill the pool
Distributive property. Hope that helps!
