Answer:A)0.5 We can see in the graph , that it is bell-shaped along x =2. A bell-shaped graph along one value is called symmetric graph and it represents a normal distribution.
Since, the give graph is symmetric around x=2, so the mean of the data is 2.
The point immediate left to the mean represents x-σ
so,
2 - σ = 1.5
So,
σ = 0.5
The sigma represents standard deviation.
Hence, Option A is correct ..
Step-by-step explanation:and what is on d is 2.5
No
Let the groups be x and 2x
Its decimal not natual so can't be divided
1 equals 0.3
2 equals 1.25
Step-by-step explanation:
Given
x - 2.6 = 1.8
x = 1.8 + 2.6
x = 4.4
