I'm sorry this question is not clear and I am not really able to answer it.
256 being rounded would become 260 and 321 would become 320 so adding up the estimates the would be 580 (real answer is 577)
Answer:
Z- score is - 2.21
Step-by-step explanation:
Given that,
Mean = 21.1
Standard deviation = 4.8
sample size (n) = 50
sample mean = 19.6
we want to find, z-score corresponding to mean of 19.6
Z = =-2.21
Z-score is -2.21
F(x)=0,-1,5,14
g(x)= -6, -1, -1, 14
g(x)=f(x)+k
-6= 0+k
K=-6
A)
B) g(x)=f(x)+k
-1=-1+ k
k=-1+1=0
> 5.0
q(x)=f(x)+k
-1=5+k
k=-1-5=-6
g×=f×+k
14= 14+k
k= 0
K=-6,0,-6,0
