Given that variance of a data set is:
Variance=σ²
the standard deviation is the square root of the variance:
thus
standard deviation= √(variance)
variance,σ²=104.04
thus
std deviation=√σ²=√104.04
thus
σ=10.2
Answer:
hi! i’m pretty sure it’s -18 and -20
Step-by-step explanation:
Answer:
k = 31
Step-by-step explanation:
