Answer:
x = 5
Step-by-step explanation:
set JN and NL equal to each other...
14x – 17 = 3x + 38
11x = 55
x = 5
Answer:
The mean of the sampling distribution of the sample proportions is 0.82 and the standard deviation is 0.0256.
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 proportions, the mean is 
and the standard deviation is 
In this problem, we have that:
.
So
The mean of the sampling distribution of the sample proportions is 0.82 and the standard deviation is 0.0256.
There are 3 choices out of 8 that include two tails. 3/8 = .375 = 37.5%
Hope this can help
Here's how to calculate the mean absolute deviation. Step 2: Calculate how far away each data point is from the mean using positive distances. These are called absolute deviations. Step 4: Divide the sum by the number of data points.
