Here, you do the same as the previous one, keeping in mind that X cuts TW in a 2:1 ratio.

Is this problem is about solving for h? If it is, here is the answer:
Answer:
0.05547
Step-by-step explanation:
Given :
_____Peter __ Alan __ Sui__total
Before 1838 __ 418 ___1475 _3731
After _ 1420 __ 329 ___1140_2889
Total _3258 __ 747 __ 2615 _6620
The expected frequency = (Row total * column total) / N
N = grand total = 6620
Using calculator :
Expected values are :
1836.19 __ 421.006 __ 1473.8
1421.81 ___325.994__ 1141.2
χ² = Σ(Observed - Expected)² / Expected
χ² = (0.00177817 + 0.0214571 + 0.000974852 + 0.00229642 + 0.0277108 + 0.00125897)
χ² = 0.05547
Answer:
y = mx + b is the answer

Answer:
1620
Step-by-step explanation:
180(n)-360=interior angle sum
180(11)-360=1620
n = number of sides
You also can divide it by 11 to know each interior angle.
1620/11=~147.27
