a population has a standard deviation of 16. if the sample of the size 64 is selcted from this popultion. what is the probability rhat the sample men will be 4 of the populatin mean

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

i would need to see the shape

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
