This exercise is asking you to find the value of
n or solve for
n, to do so you have to isolate or leave
n alone by doing different mathematical operations according to the given equation.
The given equation is
, which is a one step equation meaning that in order to solve for
n you have to perform only one mathematical operation, in this case multiplication.
or
The value of "n" in this equation is or .
Answer:
A
Step-by-step explanation:
Answer:
a) 2.66
b) 9
Step-by-step explanation:
Central Limit Theorem
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 .
part A: what is the standard deviation of the sampling distribution of x hat? show your work.
We have that . So
PartB: what does the sample size need to be if you want the standard deviation of the sampling distribution of x hat to be 2.8?
This is n when . So
Answer:
3/8 is smaller than 11/12
Step-by-step explanation:
3/8 is equal to 0.375 and 11/12 is equal to 0.91, which makes 3/8 a smaller number and 11/12 a bigger number.
Answer:D
Step-by-step explanation:
An auto repair shop charged $75/h for labor plus an additional $89 for parts.
If the shop worked for 2 h.
C = Represented the total repair cost .
Than the equation becomes
C = 75 × 2 + 89
C = 75 (2) + 89
Therefore the total cost for the repair is represented by C = 75 (2) + 89 .
Option (D) is correct .
