Answer:
No solution
Step-by-step explanation:
- 4x - 4y = 1
- 4x - 4(x + 2) = 1
- 4x - 4x - 8 = 1
- - 8 = 1
Our end result is -8 = 1. This is not true, so this system of equations have no solution.
The mean of sample means is the same as the mean of the underlying distribution.
The standard deviation of sample means is the original distribution sample mean divided by the square root of the number of samples.
Mean of sample mean distribution: 64
SD of sample mean distribution: 4/√64 = 1/2
