Hey their,
3/4
1/4
1/12
1/36
0/60
The pattern is -1/x every 2 +x/8
How i got this was 36/12=3
3*12=36
so 60-36=24
24x3/2+24=60
then 60/5=12
Hopethis helped
Answer:
(29-23)²/23 + (16-23)²/23 + (19-23)²/23 + (28-23)²/23
Step-by-step explanation:
Given :
n(American) = 29
n(Chinese) = 16
n(Mexican) = 19
n(Italian) = 28
Expected value = (29 + 16 + 19 + 28) / 4
Where, 4 = sample size
Expected value, E = 23
χ² = (Observed value - Expected value)² / expected value
χ² = (29-23)²/23 + (16-23)²/23 + (19-23)²/23 + (28-23)²/23
