You just put it in a fraction 1/10
Answer:
The sampling distribution of the sample mean of size 30 will be approximately normal with mean 15 and standard deviation 2.19.
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.
For the population, we have that:
Mean = 15
Standard deviaiton = 12
Sample of 30
By the Central Limit Theorem
Mean 15
Standard deviation 
Approximately normal
The sampling distribution of the sample mean of size 30 will be approximately normal with mean 15 and standard deviation 2.19.
Answer:
64
Step-by-step explanation:
this should be easy cause the 64 is bigger, so the parts are smaller. 192 divided by 64 is 3. 192 divided by 12 is 16. multiply, Yada yada… you get 64 is better!
Answer:
22500000000
Step-by-step explanation:
75,000 times 300,000 equals 22500000000
Answer:
c. 7, 24, 25
Step-by-step explanation:
For the formulas ...
we can use the given values of x and y to find the corresponding Pythagorean triple:
a = 4^2 -3^2 = 16 -9 = 7
b = 2·4·3 = 24
c = 4^2 +3^2 = 16 +9 = 25
The generated Pythagorean triple is (7, 24, 25), matching answer C.
