Step-by-step explanation:
Hello!
The variable of interest is:
X: visual accommodation when recognizing a speckle pattern of high-resolution CRT screen.
n= 8
Aux calculations:
∑X= 351.80
∑X²= 16528.40
To calculate the sample mean (X[bar]) you have to use the followinf formula:
X[bar]= ∑X/n= 351.80/8= 43.98
The standard deviation (S) is the square root of the variance(S²), so the first step is to calculate the variance and then the standard deviation.
S²=
S²=
S²= 151.14
S=√S²= 12.29
Diagram attached.
I hope it helps!
